Representações da mulher em telenovelas de língua portuguesa

A presente dissertação de mestrado visa reflectir acerca da construção e exposição da imagem feminina constante em três produtos de ficção, transmitidos pela televisão portuguesa desde a entrada no novo século. Considerando a televisão um dos meios de comunicação social mais dominantes da sociedade atual, a telenovela destaca-se da programação desde 1977, com a chegada de Gabriela, tornando-se, a partir de então, um dos produtos líderes de audiências, sendo portanto dos formatos mais consumidos pelos espetadores desse meio. Atua, na maior parte das vezes, como um veículo de representação social, uma forma particular de ver o mundo e um modo válido de denúncia das problemáticas sociais. A partir da transcrição de dois pequenos fragmentos de cada uma das três obras ficcionais selecionadas, pretende-se analisar e descrever os fenómenos e processos discursivos utilizados na representação das três personagens femininas, observando comportamentos e examinando relações sociais que possam conduzir à denúncia de situações de discriminação de género.

Getting Listeners Involved: Rádio Ás, a Community Web Project

[Excerpt] The idea of community is usually associated with radio today in the context of what Bart Cammaerts (2009,635) classifies as a "third type of broadcast, namely participatory radio, complementary to both commercial and public media". Following Ellie Rennie (2006, 3), community radio corresponds, as all other forms of community media, to non-profit media that provide "community members with an opportunity to participate in the production process". For the International Association for Media and Communication Research, which supports a research group on Community Communication, this area includes media that originate from, circulate and resonate with the sphere of civil society.

Modelos de negocio orientados al consumidor en los cibermedios españoles

La viabilidad de los cibermedios y los modelos de negocio que la sustenten son ya un tema  clásico  de  la  literatura  académica  y  profesional  en  el  ámbito  del  periodismo  electrónico. Consideramos relevante examinar las estrategias de ingresos orientadas al consumidor  de  los  cibermedios  españoles  en  un  contexto  de  madurez  de  la  prensa  digital que contrasta con la aguda crisis económica que vive en estos momentos el país.  Las  conclusiones  de  nuestro  estudio  señalan  la  convivencia  de  dos  modelos  de  negocio diametralmente distintos entre los cibermedios más vistos y de referencia en Internet en España y el establecimiento de estrategias de ‘suma de valor’ en aquellos cibermedios que han establecido sistemas de pago por consumo de contenidos.

Efeitos do enxofre e do boro e da inoculação em alfafa (Medicago sativa L.)

This paper deals with the results of a pot and plot experiment which was carried out to determine the influence of sulphur and boron and the effect seed inoculation with Rhizobium meliloti in the yield of alfafa. Sulphur was applied as flower of sulphur at the rates of 1,000 and 2,000 kg por hectare; boron was employed in the proportion of 15 kg of borax per hectare; both sulphur and boron were distributed broadcast before planting; the experimental design chosen for the field trial was a latin square of 6 x 6 with the following treatments: Number Treatment 1 Control 2 One dosis S + inoculation 3 Two dosis S +inoculation 4 One dosis S + B + inoculation 5 B + inoculation 6 inoculation The crop supplied four cuttings in an eleven months period. The pot experiment nearly confirmed the plot one. The following conclusions can be drawn: 1. The classification of treatments in a decrescent order was: l.o - two doses S + inoculation; 2.o - one dosis S +inoculation, S + B + inoculation, and B + inoculation (these treatmente were not statistically different); 3.o - control; 4.o - inoculation; 2 The vield due to the treatment two dosis S + inoculation was 22 per cent higher than the control one, a fact that suggests that the S supply in the soil studied ("terra roxa misturada") is not sufficient for the total requirements of alfafa; 3. From an economical point of view the best treatment was: one dosis B + inoculation which permits a net gain of Cr$ 12.527,30 per hectare per year; 4. Based on the mentioned results we recommend in soils of same type the following fertilization for alfafa. 5 tons limestone/hectare 300 kg serranafosfato and 600 kg hiperfosfato/ha 300 kg muriate of potash/ha 15 kg borax/ha and a medium organic manuring if the soil is very poor in organic matter.

Localização do adubo em relação à semente (I)

The authors discuss in the introduction the literature about the distribution and placemement of fertilizers in agricultural experiments in U.S.A. in such crops as cotton, corn, potato, beans and some vegetables. An experiment was carried out with corn in a randomized block with 7 treatments, and 4 repetitions. The plots were 11,2m wide by 10m long. The 7 treatments were the following: one broadcast, 3 applications of fertilizer in hills and 3 in rows. In the latter six treatments application in rows or hills was combined with applications in three different depths: below the seeds without mixing the soil, below the seeds but with mixing of the soil, and above the seeds without mixing the soil. The variation between treatments was significant, and the best treatment was the application of fertilizer in hill, below the seeds and with mixing of the soil. The most unfavorable was application in rows above the seed without mixing of the soil. The second best treatment was the application by broadcasting the fertilizer, with mixing the fertilizer and soil by hoeing. New experiments will be carried out, applying the fertilizer in two rows, parallel on each side to the seed row, at three depths: above, below and level with seeds planted. In their discussion the authors stress the need for more experimentation on the methods of applying fertilizers not only to corn plants, but with respect to all main crops and diferent types of soils.

Cooperative Transmission and Radio Resources Management for Wireless Networks

Report for the scientific sojourn at the Multimedia Communications Laboratory, University of Texas at Dallas, USA, from September to December 2005. The cooperative transmission has been analyzed taking a broadcast relay channel which assumes a scenario with one source and multiple destinations. Moreover, in order to improve the performance in terms of mutual information, it has been considered that for each destination there is another nearby terminal (called relay) which will help to improve the performance of the destination. This scheme combines different types of channels considered in the information theory, such as the relay channel, broadcast channel and interference channel (if the relays transmit information intended only to its associated destination). In this work, the author has studied the optimal way to encode the signals for the different users, known as capacity region (i.e. related to radio resources management ), of the broadcast relay channel.

Codificación a nivel de paquete para comunicaciones móviles por satélite

Una de les opcions que es contemplen per transmetre continguts multimèdia i proporcionar accés a Internet a grups de usuaris mòbils és fer servir satèl·lits. Les condiciones de propagació del canal mòbil impliquen que d'una manera o altra haurem de garantir la qualitat de servei. Això té fins i tot més importància si tenim en compte que, en el cas d'accés a Internet, no es té la capacitat d'assumir cert percentatge de pèrdua de dades que tenim, per exemple, en la transmissió de so o vídeo (rebaixant la qualitat). Entre les principals alternatives per a aquesta classe d’entorns es troba la inclusió de codificacions a nivell de paquet. El funcionament d'aquesta tècnica es basa en incloure a la transmissió paquets redundants, obtinguts mitjançant un determinat algoritme. El receptor podrà recuperar la informació original que es volia enviar, sempre que hagi rebut una certa quantitat de paquets, similar a la quantitat de paquets originals. A aquest mecanisme se'l coneix com Forward Error Correction (FEC) a nivell de paquet. En aquesta memòria es valoren breument les alternatives existents i s'expliquen algunes de les codificacions per a FEC més importants. A continuació es realitza un estudi compartiu d’algunes d'elles: les variants de LDPC (Low Density Parity Check) conegudes com LDGM (Low Density Generator Matrix), i la codificació Raptor

Competition between TV platforms

The aim of this paper is to identify the factors that affect the market penetration of pay television by studying the competition that exists between three types of technology (satellite, cable and ADSL). We distinguish three groups of factors: the level of market competition, the level of competition in the industry and the quality of the product being offered. Our results seem to indicate that as market concentration increases, the television service can achieve greater penetration. This relationship is specifically captured by the level of intra- and inter-platform competition. We also examine the relationship between free television channels and pay television and find that as the amount of time dedicated to the broadcasting of advertising by the former increases, the number of subscribers to pay TV rises. Finally, we examine product quality by introducing the effect of holding the rights to broadcast Professional Football League matches and an HBO or Showtime produced series. Our results suggest that these variables are critical for the penetration of pay television.

Barn owls do not interrupt their siblings

Animals communicate with conspecifics to resolve conflicts over how resources are shared. Since signals reflect individuals' resource-holding potential and motivation to compete, it is crucial that opponents efficiently transmit and receive information to adjust investment optimally in competitive interactions. Acoustic communication is particularly flexible as it can be quickly modulated according to background noise and audience. Diverse mechanisms have evolved to minimize acoustic signal interference, one being the avoidance of signal overlap by adjusting the timing of call production to alternate calls with those of competitors. However, the occurrence and function of overlap avoidance in the resolution of competition among relatives have barely been studied. Using young barn owl siblings, Tyto alba, which vocally negotiate over who will have priority access to food provided by parents, we investigated the extent to which nestlings avoid calling simultaneously and the function of this behaviour. We found that nestlings overlapped both their live siblings' calls and experimentally broadcast calls at least five times less often than expected at random. Furthermore, a focal nestling engaged more intensely in vocal negotiation when competing with nestmates that called simultaneously compared to those that did not overlap their respective calls. This suggests that barn owl nestlings avoid calling simultaneously, as overlapped calls are less efficient at deterring siblings from competing. Overlap avoidance reduces signal interference and, as a consequence, would improve the efficiency of communication among kin.

Translating and analysing songs: three songs in the context of communist Romania

Songs were the means used by the Romanian Communist Party to ‘educate’ Romanians. Through them, Romanians were told what they had to appreciate, how grateful they were supposed to be to the regime, how great President Ceausescu was and how they had to work harder and harder so that they could be even better Communists. This paper comprises the translation of three songs composed, performed and broadcast in Communist Romania and their analysis from the point of view of communication. In translating the song, I have chosen to translate closest to the original possible meaning and meanwhile to respect to the best of my ability Low’s ‘pentathlon principle’: singability, rhyme, rhythm, naturalness and fidelity to the sense of the source text
