Narrativa transmídia e a expansão do universo ficcional: os princípios e as estratégias de transmidiação da telenovela Cheias de Charme

This research analyzes the transmedia narrative television series Cheias de Charme, understood as a fictional multiplatform world, composed of several pieces distributed in different media, and into the context of media convergence. With a view to its expansion in various media controlled by production, we investigated how the principles (Jenkins 2008, 2009a, 2009b) and the strategies of expansion and spread (Fechine et al., 2013) were appropriate for fiction. To do this, literature reviews were conducted about transmidiation processes and the specifics of transmedia narrative, in order to identify possible areas of action and forms of engagement with the public. In addition, he reflected on reconfigurations of the soap opera genre in the era of participatory culture. For a better understanding of the dissertation, the observations were divided into four distinct chapters, taking as a guide and starting point the inclusion of the soap opera in the internet environment. With the aid of a descriptive research with a view to the application of the Case Study procedure in the light of Gil contributions (2010), it is believed that the proposed objectives were achieved. Finally, it was concluded that Cheias de Charme, aired by TV Globo in 2012, in time of 19h, we used creative and planned actions that have worked effectively in developing a transmedia narrative.

Morphology of Cycladophora davisiana davisiana from the Atlantic Ocean

In recent years, temporal fluctuations in the abundance of C. d. davisiana have been used frequently as a highresolution stratigraphic and paleoenvironmental tool. The modern ecology and morphologic variation (temporal and geographic) of this radiolarian species is evaluated to ascertain its potential stratigraphic and paleoenvironmental significance. Statistics were obtained on the width and height of all C. d. davisiana segments from Pleistocene populations of differing ages from the Northern Hemisphere (Labrador Sea and Iceland-Faeroe Ridge) and Southern Hemisphere (Namibian shelf and Meteor Rise). Results reveal that segment height variations between and within populations are more conservative than segment width. The mean sizes of the thorax and first abdominal segment have distinguishable differences between C. d. davisiana found in the North and South Atlantic. All populations have no significant difference in first abdominal segment width, however, mean heights of this segment differ greatly between populations of the North and South Atlantic. Second abdominal segment sizes show no clear population grouping. Size differences in post-cephalic segment size of these populations would appear to be related to some isolation of gene pools and possibly unknown paleoenvironmental factors. Temporal changes in the postcephalic size of C. d. davisiana may be used to: (1) identify temporally equivalent peaks in abundance of the species in a given region, (2) possibly evaluate the degree of mixing of water'masses between regions, and (3) trace the initial spread of the species from its area of origin. Cleve's 1887 plankton samples, between Greenland and Spitzsbergen, were studied and used in conjunction with other data to make the following conclusions on the modern ecology of C. d. davisiana in the Arctic and Greenland-Norwegian Seas. (1) It is presently absent in surface water plankton samples, (2) it currently lives at depths below 500 m, where it is rare, (3) it does not live in the upper 200 m under Arctic ice but is rare at greater depths, (4) it is absent in the upper 200 m near permanent Greenland Sea ice where normal oceanic salinity prevails, and (5) it is most common in deep marginal fjord environments which may serve as a refuge for the species during interglacial periods. In the Atlantic Ocean, the abundance of C. d. davisiana does not exceed 1% of the assemblage between the Subtropical Convergence of each hemisphere. In the Norwegian and Labrador Seas the species may occasionally be in the range of 1-5% of the modern radiolarian assemblage and never more than 5% in the southern high latitudes. Apparently only in the modern Sea of Okhotsk, does the species presently occur in high abundance. We concur with Morley and Hays (1983) that increased abundances are likely caused by the development of a strong low-salinity surface layer associated with seasonal sea ice melting and a strong temperature minimum above warmer and higher salinity intermediate waters. Similar conditions were frequent during the Pleistocene in the high latitudes and its modern scarcity outside the Sea of Okhotsk must be related to the absence of the presently unique conditions in the latter region.

Investigation of PHY, MAC and APP layers for adaptive and cross-layer optimization in IEEE802.11 WLAN

Due to huge popularity of portable terminals based on Wireless LANs and increasing demand for multimedia services from these terminals, the earlier structures and protocols are insufficient to cover the requirements of emerging networks and communications. Most research in this field is tailored to find more efficient ways to optimize the quality of wireless LAN regarding the requirements of multimedia services. Our work is to investigate the effects of modulation modes at the physical layer, retry limits at the MAC layer and packet sizes at the application layer over the quality of media packet transmission. Interrelation among these parameters to extract a cross-layer idea will be discussed as well. We will show how these parameters from different layers jointly contribute to the performance of service delivery by the network. The results obtained could form a basis to suggest independent optimization in each layer (an adaptive approach) or optimization of a set of parameters from different layers (a cross-layer approach). Our simulation model is implemented in the NS-2 simulator. Throughput and delay (latency) of packet transmission are the quantities of our assessments. © 2010 IEEE.

A review of road structure data in six European countries

The European Union has expanded significantly in recent years. Sustainable trade within the Union, leading to economic growth to the benefit of the ‘old’ and ‘new’ member states is thus extremely important. The road infrastructure is strategic and vital to such development since an uneven transport infrastructure, in terms of capacity and condition, has the potential to reinforce uneven development trends and hinder economic convergence of old and new member states. In the decades since their design and construction, loading conditions have significantly changed for many major highway infrastructure elements/networks owing primarily to increased freight volumes and vehicle sizes. This, coupled with the gradual deterioration of a significant number of highway structures due to their age, and the absence of a pan-European assessment framework, can be expected to affect the smooth functioning of the infrastructure in its as-built condition. Increased periods of reduced flow can be expected owing to planned and unplanned interventions for repair/rehabilitation. This paper reports the findings of a survey regarding the current status of the highway infrastructure elements in six countries within the European Union as reported by the owners/operators. The countries surveyed include a cross-section of ‘existing’ older countries and ‘new’ member states. The current situations for bridges, culverts, tunnels and retaining walls are reported, along with their potential replacement costs. The findings act as a departure point for further studies in support of a centralised and/or synchronised EU approach to infrastructure maintenance management. Information in the form presented in this paper is central to any future decision-making frameworks in terms of trade route choice and operations, monetary investment, optimised maintenance, management and rehabilitation of the built infrastructure and the economic integration of the newly joined member states.

Total synthesis of furospongolide and related furanolipid analogues as potential anti-tumour agents

This thesis details the design, development and execution of innovative methodology in the total synthesis of the terpene-derived marine natural product, furospongolide. It also outlines the synthetic routes used to prepare a novel range of furanolipids derivatives and subsequent evaluation of their potential as antitumour agents. The first chapter is a review of the literature describing efforts undertaken towards the synthesis of biologically active furanosesterterpenoid marine natural products. A brief discussion on the sources and biological activity exhibited by furan natural products is also provided. In addition, a concise account of the role of hypoxia in cancer, and the increasing interest in HIF-1 inhibition as a target for chemotherapeutics is examined. The second chapter discusses the concise synthesis of the marine HIF-1 inhibitor furospongolide, which was achieved in five linear steps from (E,E)-farnesyl acetate. The synthetic strategy features a selective oxidation reaction, a Schlosser sp3-sp3 cross-coupling, a Wittig cross-coupling and an elaborate one-pot selective reduction, lactonisation and isomerization reaction to install the butenolide ring. The structure-activity relationship of furospongolide was also investigated. This involved the design and synthesis of a library of structurally modified analogues sharing the same C1-C13 subunit. This was achieved by exploiting the brevity and high level of convergence of our synthetic route together with the readily amenable structure of our target molecule. Exploiting the Schlosser cross-coupling allowed for replacement of furan with other heterocycles in the preparation of various furanolipid and thiophenolipid derivatives. The employment of reductive amination and Wittig chemistry further added to our novel library of structural derivatives. The third chapter discusses the results obtained from the NCI from biological evaluation From a collection of 28 novel compounds evaluated against the NCI-60 cancer cell array, six drug candidates were successfully selected for further biological evaluation on the basis of antitumour activity. COMPARE analysis revealed a strong correlation between some of our design analogues and the blockbuster anticancer agent tamoxifen, further supporting the potential of furanolipids in the treatment of breast cancer. The fourth chapter, details the full experimental procedures, including spectroscopic and analytical data for all the compounds prepared during this research.

Scaling limits of a model for selection at two scales

The dynamics of a population undergoing selection is a central topic in evolutionary biology. This question is particularly intriguing in the case where selective forces act in opposing directions at two population scales. For example, a fast-replicating virus strain outcompetes slower-replicating strains at the within-host scale. However, if the fast-replicating strain causes host morbidity and is less frequently transmitted, it can be outcompeted by slower-replicating strains at the between-host scale. Here we consider a stochastic ball-and-urn process which models this type of phenomenon. We prove the weak convergence of this process under two natural scalings. The first scaling leads to a deterministic nonlinear integro-partial differential equation on the interval $[0,1]$ with dependence on a single parameter, $\lambda$. We show that the fixed points of this differential equation are Beta distributions and that their stability depends on $\lambda$ and the behavior of the initial data around $1$. The second scaling leads to a measure-valued Fleming-Viot process, an infinite dimensional stochastic process that is frequently associated with a population genetics.

SDN enabled dynamically reconfigurable high capacity optical access architecture for converged services

Dynamically reconfigurable time-division multiplexing (TDM) dense wavelength division multiplexing (DWDM) long-reach passive optical networks (PONs) can support the reduction of nodes and network interfaces by enabling a fully meshed flat optical core. In this paper we demonstrate the flexibility of the TDM-DWDM PON architecture, which can enable the convergence of multiple service types on a single physical layer. Heterogeneous services and modulation formats, i.e. residential 10G PON channels, business 100G dedicated channel and wireless fronthaul, are demonstrated co-existing on the same long reach TDM-DWDM PON system, with up to 100km reach, 512 users and emulated system load of 40 channels, employing amplifier nodes with either erbium doped fiber amplifiers (EDFAs) or semiconductor optical amplifiers (SOAs). For the first time end-to-end software defined networking (SDN) management of the access and core network elements is also implemented and integrated with the PON physical layer in order to demonstrate two service use cases: a fast protection mechanism with end-to-end service restoration in the case of a primary link failure; and dynamic wavelength allocation (DWA) in response to an increased traffic demand.

Understanding Media Production: A rejoinder to Murdock and Golding

This article is a rejoinder to Murdock and Golding’s response to my critique of the political economy of communications (PEC) analysis of media production (see Author 2015). This article sets this exchange in the context of a broader debate in recent editions of Media, Culture & Society (Garnham 2016, Fuchs, 2016) about the value of PEC. Much of this debate stems from Garnham’s (2011) critical review of 40 years of PEC research.

Breaking Open the Black Boxes: media archaeology, anarchaeology and media materiality

An essay on the emergent methodology of media archaeology, in realtion to the material turn in approaches to digital media. In particular, this article advocates taking up Siegfried Zielinski's concept of 'anarchaeology', but in a different sense to the way it was originally proposed, in order to emphasise the political potentials of a media (an)archaeological methodological approach.

Diversity and television in Argentina: the case of the Audiovisual Technology Hub Programme

This paper describes and analyses the Audiovisual Technology Hub Programme (Programa Polos Audiovisuales Tecnológicos - PPAT), which has been implemented in Argentina between 2010 and 2015 as part of the public policy of former administration of Cristina Fernández de Kirchner. The main goal was to promote a television industry that reflects the cultural diversity of Argentina by dividing the national territory in nine into nine audiovisual technology hubs, where national public universities acted as centres that gathered a range of regional stakeholders. Considering the 18 TV seasons that were produced for television between 2013 and 2014, the text analyses the diversity of sources and genres / subgenres and its restricted marketing. The article closes with a brief set of conclusions about this initiative.

Measuring the Diversity and the Integration of Film Production in Mercosur: A Social Network Analysis

Based on an original and comprehensive database of all feature fiction films produced in Mercosur between 2004 and 2012, the paper analyses whether the Mercosur film industry has evolved towards an integrated and culturally more diverse market. It provides a summary of policy opportunities in terms of integration and diversity, emphasizing the limiter role played by regional policies. It then shows that although the Mercosur film industry remains rather disintegrated, it tends to become more integrated and culturally more diverse. From a methodological point of view, the combination of Social Network Analysis and the Stirling Model opens up interesting research tracks to analyse creative industries in terms of their market integration and their cultural diversity.

Asumiendo las consecuencias negativas de la adicción al juego

La adicción al juego no sólo se caracteriza por la pérdida de control ante el juego, sino que esta conducta tiende a generar problemas en los diferentes ámbitos de la vida del ludópata. Por ello, este aspecto se recoge en el Manual diagnóstico y estadístico de los trastornos mentales-5 (DSM-V) como uno de los criterios para realizar su valoración diagnóstica. Objetivo: describir y analizar los diferentes elementos que conforman la compleja problemática aparejada a esta adicción y que pueden terminar en situaciones de exclusión social. Método: Se opta por una metodología cualitativa que se ajusta mejor a los intereses del estudio. Como técnica se ha seleccionado la historia de vida, instrumento de evaluación que permite conocer la verdadera magnitud del problema desde el punto de vista de los afectados. Resultados. De manera general, se ha descubierto que ser ludópata tiene muchos más consecuentes que el problema económico evidente. No debemos despreciar las implicaciones de esta conducta a otros niveles: familiar, laboral, legal y social, que pueden considerarse, a medio plazo, como factores mucho más execrables que el del mero gasto económico. Conclusión. Es fácil avistar que los graves problemas que acarrea la adicción al juego son capaces de desmembrar el proyecto vital del ludópata y el de su familia. Todo vale, aunque para ello tenga que jugarse su puesto de trabajo, su casa, su familia, sus amistades, su estatus social y su propia dignidad.

Narrativa periodística en la convergencia de medios

El de hoy es un entorno en el que todos los días los medios sufren cambios estructurales y funcionales que los obligan a replantear su accionar y reinventar sus usos y esquemas de comunicación, de ahí la importancia de esta investigación mixta, cuantitativa y cualitativa, que recurrió a seguimiento en redes sociales y análisis de contenidos; detectando el cómo los medios responden al estar inmersos en un mundo en el que se pasó de una cultura de imprenta a una cultura de la pantalla donde surgen nuevas prácticas sociales que crean dispositivos a la medida de cada uno, elementos en los que conjugan el texto, el audio y el video configurando nuevos medios en los que se generan otras formas de interacción, y se replantea el quehacer profesional del Comunicador Social Periodista.

Investigative journalism in Mexico: between ideals and realities. The case of Morelia

The aim of this paper is to analyse the state of the investigative journalism in Mexico, especially the one that is practiced at the local level in the provinces. That is, this research is based upon a case study conducted in Morelia, the capital city of the state of Michoacán. The empirical evidence will show that there is an evident divergence regarding the practice of the investigative journalism: on the one hand, journalists are aware of what this concept involves and they consider that they practice it on a regular basis; but, on the other, the content analysis prove otherwise. In other words, the account of what is actually printed significantly differs from the news workers’ perceptions, because the former shows a poorly developed journalistic investigation practice.
