Tom Riley and Althea Silvera Packing the Charles Perry Papers

This photo shows Betty Perry, Tom Riley, and Althea Silvera in the floor packingthe Charles Perry Papers in the Perry Palm Beach home. Charles Perry donated his papers of his time as president of the university to the FIU library where they are held in the archives. An interview, filmed by Richard Pabon and Elizabeth Marsh from FIU’s Broadcast Video Production team, recorded this event. Charles Edward Perry (Chuck), 1937-1999, was the founding president of Florida International University in Miami, Florida. He grew up in Logan County, West Virginia and received his bachelor's and masters's degrees from Bowling Green State University. He married Betty Laird in 1961. In 1969, at the age of 32, Perry was the youngest president of any university in the nation. The name of the university reflects Perry’s desire for a title that would not limit the scope of the institution and would support his vision of having close ties to Latin America. Perry and a founding corps opened FIU to 5,667 students in 1972 with only one large building housing six different schools. Perry left the office of President of FIU in 1976 when the student body had grown to 10,000 students and the university had six buildings, offered 134 different degrees and was fully accredited. Charles Perry died on August 30, 1999 at his home in Rockwall, Texas. He is buried on the FIU campus in front of the Graham Center entrance.

Characterization of Atlantic Cod Spawning Habitat and Behavior in Icelandic Coastal Waters

The physical habitat used during spawning may potentially be an important factor affecting reproductive output of broadcast spawning marine fishes, particularly for species with complex, substrate-oriented mating systems and behaviors, such as Atlantic cod Gadus morhua. We characterized the habitat use and behavior of spawning Atlantic cod at two locations off the coast of southwestern Iceland during a 2-d research cruise (15–16 April 2009). We simultaneously operated two different active hydroacoustic gear types, a split beam echosounder and a dual frequency imaging sonar (DIDSON), as well as a remotely operated underwater vehicle (ROV). A total of five fish species were identified through ROV surveys: including cusk Brosme brosme, Atlantic cod, haddock Melanogrammus aeglefinus, lemon sole Microstomus kitt, and Atlantic redfish Sebastes spp. Of the three habitats identified in the acoustic surveys, the transitional habitat between boulder/lava field and sand habitats was characterized by greater fish density and acoustic target strength compared to that of sand or boulder/lava field habitats independently. Atlantic cod were observed behaving in a manner consistent with published descriptions of spawning. Individuals were observed ascending 1–5 m into the water column from the bottom at an average vertical swimming speed of 0.20–0.25 m s−1 and maintained an average spacing of 1.0–1.4 m between individuals. Our results suggest that cod do not choose spawning locations indiscriminately despite the fact that it is a broadcast spawning fish with planktonic eggs that are released well above the seafloor.

A reportagem nas rádios comerciais de Natal-RN

This thesis aims to investigate the space of radio reporting and production conditions in radio newscasts in commercial stations operating in modulated frequency (FM) in the city of Natal, Rio Grande do Norte. Through preliminary empirical observation, it was observed that this journalistic style (radio reportage) is hardly present in the schedule of local commercial radio stations, with a lack of in-depth news coverage. The research is based on the content broadcast in four daily radio news programs transmitted by commercial stations. It raises the hypothesis that the crisis that cuts across journalistic companies could be justified by the lack of financial funding in in-depth news reporting. The starting point for the case study (Yin, 2005) was a bibliographical research, for building a theoretical model of reference for the studied style, based on Prado (1989), Bespalhok (2006), Meditsch (2007), Lopes (2013) and Ferraretto (2014). The methodology also included listening to content broadcast during a week in the four analyzed news programs, participant observation and interviews with professionals who produce these programs. There were eight events with similar characteristics to radio reporting, all broadcast in just one of the analyzed programs. According to the interviewees, the format is rarely used because it would generate high businesses costs, which are prohibitively high for the stations. The research also inferred that besides the lack of entrepreneurial vision, there is accommodation of the professionals who could produce news stories even with little structure available. Finally, this work points out the need to invest more on local radio journalism to improve the quality of the information provided on commercial broadcasters in Natal and the training of journalism students to use radio's potential to maximum use.

Serviço de videochamada utilizando o padrão o HbbTV: myPhoneOnTV

Nos últimos anos tem-se verificado que a população portuguesa está cada vez mais envelhecida. Este fator agrava-se em ambientes rurais, onde a desertificação populacional é mais frequente, derivado, entre outros, da migração da população mais jovem para os grandes centros urbanos, em busca de melhores condições de vida. Tendo como consequência a exclusão social da população residente nestas zonas. O reduzido foco populacional das zonas rurais não é um fator atrativo para as entidades que realizam investimentos em serviços e infraestruturas tecnológicas, devido ao retorno financeiro obtido não ser, à partida, rentável. Levando a uma exclusão tecnológica de quem reside nestas zonas. Este fator, agrava-se na população sénior dado que raramente são estimulados a interagir com a tecnologia. Com o objetivo de contribuir para a melhoria desta problemática, combatendo simultaneamente os dois tipos de exclusões, tecnológica e social, propõem-se através desta dissertação, um serviço de videochamada, baseado no conceito do padrão Hybrid Broadcast Broadband TV (HbbTV). Um dos fatores considerados, durante o estudo deste serviço, foi a barreira tecnológica existente entre os idosos e a tecnologia. De modo a aproximar ambos, optou-se por aproveitar os conhecimentos que os idosos já possuem na utilização de equipamentos do seu quotidiano. Sendo a televisão, o equipamento selecionado para integrar no serviço de videochamada, permitindo ao idoso contactar facilmente com outras pessoas e serviços. Através da implementação de um protótipo e dos resultados obtidos, conclui-se que o serviço desenvolvido é uma solução válida para combater a problemática apresentada, contribuindo positivamente para a redução da exclusão social e da iliteracia tecnológica

Weathering the crisis? Managing democracy at a national broadcaster

With post-2008 political and economic crises as its backdrop, this inquiry into the political roles and functions of public service broadcasting (PSB) in Ireland is principally concerned with examining the capacities for and actuality of critical and counter-hegemonic professional journalistic and institutional mediations of crisis. Recognising the diversity of influences on the normative identity of Irish PSB, the dissertation adopts a sociological approach that acknowledges the systemic embedding of media institutions in the broader field of power. An initial tracing of the formative impacts of endogenous and exogenous forces on the democratic horizons of PSB suggests that the present crisis conjuncture does not represent promising terrain for engendering critical crisis and recovery imaginaries. A methodologically diverse intra-institutional empirical research agenda aims to explore at close hand Irish PSB’s contingent navigation of crisis, encompassing ethnographic observation in the newsroom, practitioner interviews and textual analysis of broadcast output. These methods afford close analysis of practices of journalistic production and reflexivity, self-conceptions of the journalistic habitus, and ideological affinities of crisis framings in broadcast output. These analyses are supplemented by a participant observation study of the possibilities for public agenda-building in a key institutional venue of public participation in broadcasting governance. The findings offer an evidential basis for the arguments that the crisis has prompted only minimal changes to professional norms and practices of representation and inclusion; that journalistic crisis framings tend toward effecting hegemonic repair by lending support to neoliberal crisis and recovery imaginaries; and that the institutional openings for the building of public counterpower are highly constrained. The overall conclusion is made that the normative democratic orientation embedded in the professional and institutional projects of public service broadcasting help render it ill-equipped to act as a re-democratising countervailing power against the democratic regressions engendered by the present crisis of democratic capitalism.

Screening the RSC stage: the 2014 Live from Stratford-upon-Avon cinema broadcasts

During the Royal Shakespeare Company's 2014 summer season, both parts of Henry IV and The Two Gentlemen of Verona were presented as Live from Stratford-upon-Avon broadcasts in cinemas around the world. This article presents a case study of these broadcasts, drawing on the author's observations and insights as their producer as well as interview contributions from those involved in both the stage and screen presentations. Recognising that the hybrid form of “live cinema” performance has developed rapidly over the past five years but is as-yet little-documented, the study develops an analytical approach to its creative processes and to its aesthetics. This discussion is combined with a consideration of the history of earlier screen adaptations of RSC productions at Stratford-upon-Avon. The article details the stages of the production process for the Live from Stratford-upon-Avon broadcasts in 2014 and considers the ways in which the broadcast teams collaborate with the casts and creative teams of the theatre productions. In addition, the article explores processes of adaptation in the journey from stage to screen, the poetics of multi-camera presentation and questions of “live-ness”, the social experience of viewing performance in the cinema, and possible developments for live theatre on screen.

Estructura formal, textual y oral del discurso público

Estructura formal, textual y oral del discurso públicoExisten tres competencias comunicativas muy valoradas en la sociedad de la información. Primero, la búsqueda, selección y gestión de grandes cantidades de información. Segundo, la redacción de textos claros, concisos y rigurosos. Y en tercer lugar, la exposición y defensa oral de esta información en un discurso público. Tradicionalmente, los estudios de periodismo han abordado estas competencias de forma independiente. Pero actualmente, instituciones y empresas de ámbitos diferentes demandan un perfil profesional capaz de aplicarlas ante cualquier tipo de información y con objetivos diversos. Se propone un modelo integral en tres niveles estructurales basado en teorías, conceptos y estudios específicos de periodismo, oratoria, retórica… o comunicación, en los últimos años. Este modelo puede contribuir a encauzar las investigaciones de académicos y representa una herramienta de entrenamiento para profesionales.

Wireless Networks with Energy Harvesting and Power Transfer: Joint Power and Time Allocation

In this letter, we consider wireless powered communication networks which could operate perpetually, as the base station (BS) broadcasts energy to the multiple energy harvesting (EH) information transmitters. These employ “harvest then transmit” mechanism, as they spend all of their energy harvested during the previous BS energy broadcast to transmit the information towards the BS. Assuming time division multiple access (TDMA), we propose a novel transmission scheme for jointly optimal allocation of the BS broadcasting power and time sharing among the wireless nodes, which maximizes the overall network throughput, under the constraint of average transmit power and maximum transmit power at the BS. The proposed scheme significantly outperforms “state of the art” schemes that employ only the optimal time allocation. If a single EH transmitter is considered, we generalize the optimal solutions for the case of fixed circuit power consumption, which refers to a much more practical scenario.

Joint Information and Jamming Beamforming for Secrecy Rate Maximization in Cognitive Radio Networks

In this paper, we consider the secure beamforming design for an underlay cognitive radio multiple-input singleoutput broadcast channel in the presence of multiple passive eavesdroppers. Our goal is to design a jamming noise (JN) transmit strategy to maximize the secrecy rate of the secondary system. By utilizing the zero-forcing method to eliminate the interference caused by JN to the secondary user, we study the joint optimization of the information and JN beamforming for secrecy rate maximization of the secondary system while satisfying all the interference power constraints at the primary users, as well as the per-antenna power constraint at the secondary transmitter. For an optimal beamforming design, the original problem is a nonconvex program, which can be reformulated as a convex program by applying the rank relaxation method. To this end, we prove that the rank relaxation is tight and propose a barrier interior-point method to solve the resulting saddle point problem based on a duality result. To find the global optimal solution, we transform the considered problem into an unconstrained optimization problem. We then employ Broyden-Fletcher-Goldfarb-Shanno (BFGS) method to solve the resulting unconstrained problem which helps reduce the complexity significantly, compared to conventional methods. Simulation results show the fast convergence of the proposed algorithm and substantial performance improvements over existing approaches.

RF energy harvesting two-way cognitive DF relaying with transceiver impairments

This paper analyzes the impact of transceiver impairments on outage probability (OP) and throughput of decode-and-forward two-way cognitive relay (TWCR) networks, where the relay is self-powered by harvesting energy from the transmitted signals. We consider two bidirectional relaying protocols namely, multiple access broadcast (MABC) protocol and time division broadcast (TDBC) protocol, as well as, two power transfer policies namely, dual-source (DS) energy transfer and single-fixed-source (SFS) energy transfer. Closed-form expressions for OP and throughput of the network are derived in the context of delay-limited transmission. Numerical results corroborate our analysis, thereby we can quantify the degradation of OP and throughput of TWCR networks due to transceiver hardware impairments. Under the specific parameters, our results indicate that the MABC protocol achieves asymptotically a higher throughput by 0.65 [bits/s/Hz] than the TDBC protocol, while the DS energy transfer scheme offers better performance than the SFS policy for both relaying protocols.

An Efficient Precoder Design for Multiuser MIMO Cognitive Radio Networks with Interference Constraints

We consider a linear precoder design for an underlay cognitive radio multiple-input multiple-output broadcast channel, where the secondary system consisting of a secondary base-station (BS) and a group of secondary users (SUs) is allowed to share the same spectrum with the primary system. All the transceivers are equipped with multiple antennas, each of which has its own maximum power constraint. Assuming zero-forcing method to eliminate the multiuser interference, we study the sum rate maximization problem for the secondary system subject to both per-antenna power constraints at the secondary BS and the interference power constraints at the primary users. The problem of interest differs from the ones studied previously that often assumed a sum power constraint and/or single antenna employed at either both the primary and secondary receivers or the primary receivers. To develop an efficient numerical algorithm, we first invoke the rank relaxation method to transform the considered problem into a convex-concave problem based on a downlink-uplink result. We then propose a barrier interior-point method to solve the resulting saddle point problem. In particular, in each iteration of the proposed method we find the Newton step by solving a system of discrete-time Sylvester equations, which help reduce the complexity significantly, compared to the conventional method. Simulation results are provided to demonstrate fast convergence and effectiveness of the proposed algorithm.
