Usabilidade: um fator crítico para da interatividade da televisão digital

Este artigo tem por objetivo fazer uma reflexão da usabilidade aplicada à interatividade do SBTVD (Sistema Brasileiro de Televisão Digital). Aborda as perspectivas de mercado no Brasil e na América Latina e cita alguns casos em que a usabilidade constituiu-se em fator decisivo para ampliar o ciclo de vida do produto. Explicita a interação e a engenharia de usabilidade com destaque para a garantia da consolidação da interatividade do SBTVD. Neste contexto, inclui o estabelecimento de redes de banda larga para todos, chamados de “cidade digital” condição decisiva no processo de possibilitar a democratização. Conclui que essa facilidade de usabilidade, aliada aos avanços tecnológicos digitais que propiciam uma qualidade e uma convergência tecnológica, que certamente romperá o modelo de telespectador passivo para um telespectador interativo gerando um novo contingente de telespectadores vindo da televisão digital e da televisão analógica.

Ocurrence of male morphotypes of Macrobrachium amazonicum (Caridea, Palaemonidae) in a population with an entirely freshwater life cycle

This study records, for the first time, the occurrence of all four male morphotypes in a population of Macrobrachium amazonicum from a continental environment, with an entirely freshwater life cycle. The specimens studied came from the Tietê River, state of São Paulo, Brazil, and were collected in a lotic environment downstream from Ibitinga Dam. This population was compared with other continental populations, including a population from the dam itself, collected in a previous study. Four samples of 30 minutes were taken monthly, using a trap, from January to April 2011. Each male specimen was measured with respect to seven body dimensions as follows: carapace length (CL), right cheliped length (RCL), dactyl length (DCL), propodus length (PPL), carpus length (CRL), merus length (ML) and ischium length (IL). The relative growth was analyzed based on the change in growth patterns of certain body parts in relation to the independent variable CL. The four male morphotypes proposed for the species were found using morphological and morphometric analyses. Different biological characteristics were found between the populations studied. The male population of the lake of Ibitinga and from Pantanal presented mean sizes and number of morphotypes lower than the population studied here. These differences seem to be closely related to ecological characteristics of the environments inhabited by these populations. Our results supported the hypothesis that coastal and continental populations of M. amazonicum belong to the same species.

Tempo de trânsito gastrointestinal de diferentes frutos e taxa de germinação de Morus nigra pós passagem pelo trato em Sabiás-barranco (Turdus leucomelas)

Seed dispersal is a key process in the life cycle of plant species and may determine the dynamics of their populations. The passage of the fruit from the gastrointestinal tract brings effects on energy and nutritional rewards for the bird. The retention time of the seeds is an essential factor for the dispersion, affecting the dispersal distance. Some factors determine it, as the size of the bird, degree of frugivory, chemical composition of the fruit, the number and size of seeds. The study sought to characterize the Morus nigra seed retention time in three species of thrushes and compare them with other species of birds and plants. The blackberry, exotic species with socio-economic importance in Brazil, produces aggregate fruit having up to 60 seeds. Have been kept in captivity individuals leucomelas Turdus rufiventris thrush, thrush and amaurochalinus, native and omnivorous species, important dispersers in degraded areas, inhabiting the urban and the natural environment. In 274 samples of feces was recorded about 500 mulberry seeds. The first record of seeds was in 15 minutes (n = 2) and the last to 115 minutes (n = 4) after eating the fruit. The average time of gastrointestinal transit of seed for the three species was 52 minutes and 80% were defecated to 65 minutes post ingestion. Taking into consideration the type of fruit and the species of bird, there is great variation in the retention time when compared to other species of birds, being in general slower. That way, can be increase the degree of dispersion of the seed to more distant areas of the mother plant, increasing the chances of survival of seedlings, according to the hypothesis Janzen and Connell. The Turdus It showed efficient dispersers Morus nigra seeds, and inhabits natural and urbanized environment, the possibility of exchange of these seeds between environments by the action of thrushes

Comunicação e coolhunting: os caçadores de tendências sob o olhar das relações públicas

The anticipation of trends has become vital in today's market due to the shortening of product life cycle. For this reason, the organizations need to be alert to ongoing changes so as to satisfy the consumer market. Given the current profile of these consumers, the reducing of the products life cycle and the transformations of cultural and social aspects, has developed the coolhunting research that uses different processes from those used by traditional trends research and focuses the analysis in the young public. This work investigates the characteristics of this new research proposal in the contemporary society and your rise in the coming years, In addition to relating the work of Public Relations in this innovative proposal

A família e o indivíduo no curso vital: compreensão trigeracional sobre a morte e o morrer

The death has been considered a forbidden issue. To develop studies that promote reflections about it allows the enlargement of the understanding as regarding the death as about life in that both are related during the human existence. This research aimed to understand the death’s conceptions and family meanings to three different generations. For this goal, through phenomenological methodology, were achieved individual interviews with adolescents, both his parents and the grandfather, all belonging to the same family. After to understand the participant’s experiences, six thematic categories were created: a) Death’s meanings; b) The death of himself; c) The death of another and/or its possibility; d) Sources of support; e) The family in the death’s presence; f) The life in the death’s inevitability presence. From these categories, the dates were phenomenologically. The participants showed similar reports in several times, confirming the literature that says that the daily life experiences among the family members take the family to form a peculiar way to understand and an interpret their experiences. This identity family, however, did not prevent each participant to develop his particular history based in idiosyncratic elements and associated with the stage of life cycle that it is. The reports showed that the prohibition of death in society is still very present, which prevents that discussions about the issue are present in daily life. This study provided for participants to reflect on their experiences around the phenomenon of death and, consequently, about the inseparable relationship between living and dying. It has also reiterated the literature, showing the similarity of views among the family members of three generations face a vital phenomenon potentially impacting the life cycle of individual and family.

A utilização da tecnologia nas artes, design e engenharia, como ferramenta de vanguarda e sustentabilidade

Art can be understood as a process in which knowledge is used to perform certain skills. From Latin ARS, technical means and / or ability, in Greece, there was the word art, but "Tekne", which originated from the word "technical." So art and technique are present in sculptures, paintings, shoes or ships. In this sense, designers, engineers and all professionals who use technology can be called artists. Considerations must be made regarding the level of energy embedded in the material from its production until its use, even considering recycling, sustainability and life cycle of materials. This study aimed to present the use of scanning technology and 3D virtual modeling and its application in prototyping with CNC (Computed Numerical Control) as a tool in current use cutting-edge courses in arts, design and engineering and their relations with sustainability.

Life cycle assessment applied to municipal solid waste management: a case study

This study analyzes the environmental performance of the Municipal Solid Waste Management System (MSWMS) of Piedade, São Paulo, from a systemic perspective. A life cycle assessment (LCA) technique was applied according to an attributional approach to evaluate both the current operational situation and different prospective scenarios, which were devised based on the application of targets for recycling dry and wet waste suggested by the pre-draft version of the Brazilian Plan for Solid Waste. The life cycle impact assessment method EcoIndicator 99, in association with normalization and weighting procedures, was used to conduct the analysis. It was observed that the adoption of goals of 30%, 50% and 70% for recovering of the recyclable dry waste, resulted in improvement of the environmental performance of the waste management system under analysis, respectively of 10%, 15% and 20%. It was also possible to detect an evolution in the order of 54% in reducing impacts resulting from the adoption of targets for composting. LCA proved to be effective for the evaluation of the environmental performance of MSWMS-Piedade. However, for future evaluations, the attributional approach should be replaced by the methodological practice of substitution to enable the avoided burdens to be considered in estimations of the environmental performance municipal solid waste management systems.
