É difícil conseguir captar a essência das dietas mediáticas e do pensamento dos cidadãos sobre a democracia, ido além da visão mais tradicional, associada a um pensamento de sentido negativo e de afastamento. Neste artigo indicamos as vantagens de optar por metodologias qualitativas participativas e longitudinais, que permitem melhor apreender atitudes e hábitos e os contextos do quotidiano em que se desenvolvem. Estas opções possibilitam melhor conhecer espaços de micro análise e ainda favorecer ambientes em que os participantes na pesquisa sentem que dão um contributo ativo para o desenrolar da investigação. Por esta via, consegue-se apreender melhor processos de ligação entre jornalismo e democracia, tendo uma das conclusões deste estudo apontado para processos de ligação próxima entre opiniões sobre jornalismo, democracia e contextos quotidianos. Os jovens que indicaram ter uma visão mais alargada sobre o jornalismo, designadamente percepcionando as suas ambivalências e considerando-as inerentes à profissão, foram também os que revelaram maior capacidade para entender a política numa visão alargada do seu significado.

This article critically resumes Ricardo's principle of comparative advantages pointing out internal coherence problems that have been neglected by the specialized literature. First, long-lasting disequilibria observed in the balance of trade seem incompatible with the idea that these disequilibria are caused by technical advances that change relative prices. Second, comparative advantages do not seem to work in an economy with a universally accepted commodity-money. Finally, the contradiction between the gold standard mechanisms, ruled by Smith's "Law of Reflux", and the quantitative theory of money, which is a necessary condition for the "second way" of the theory of comparative advantages.

One way of exploring the power of sound in the experience and constitution of space is through the phenomenon of personal listening devices (PLDs) in public environments. In this thesis, I draw from in-depth interviews with eleven Brock University students in S1. Catharines, Ontario, to show how PLDs (such as MP3 players like the iPod) are used to create personalized soundscapes and mediate their public transit journeys. I discuss how my interview participants experience the space-time of public transit, and show how PLDs are used to mediate these experiences in acoustic and non-acoustic ways. PLD use demonstrates that acoustic and environmental experiences are co-constitutive, which highlights a kinaesthetic quality of the transit-space. My empirical findings show that PLDs transform space, particularly by overlapping public and private appropriations of the bus. I use these empirical findings to discuss the PLD phenomenon in the theoretical context of spatiality, and more specifically, acoustic space. J develop the ontological notion of acoustic space, stating that space shares many of the properties of sound, and argue that sound is a rich epistemological tool for understanding and explaining our everyday experiences.

Transport systems involved the use of territory in different Brazilian cities with regard to the occupation of road systems in urban areas. The implementation of systems engineering and transport infrastructure such as roads (roads), signs, stops, stations and complex road (bridges, viaducts and tunnels) are not used in the same way in the area. The subway is not even use the bus and vice versa. The time spent in travel, the time to access and the number of trips made by passengers in each way of transport is not the same. The use of transport systems in the territory, therefore, takes place through a whole in the current period we are in the technicalscientific and informational. This work addresses, however, the area used as a synonym of geographical area, analyzed by two categories of analysis, systems of objects formed by the fixed and the systems formed by the action flows. The system analyzed is the public transport by bus and population displacement that makes using this medium with source destination from home to work and has as empirical cut the Lagoa Azul located in the district administrative area north of Natal / RN. The general objective of this research is to understand the extent to which public transport has contributed to the socio-spatial accessibility of the residents of Barrio Blue Lagoon, located in Natal-RN, emphasizing the way home and the workplace. To reach the general objective of this dissertation, a study was made in light of the line which the methodological empirical facts, statistical data and theoretical knowledge of the events that occur in the quarter related to the Lagoa Azul economic aspects. Use for this, the concepts of mobility and Accessibility

Purpose: to compare in a retrospective way, 51 women who underwent tubal ligation, 30 through microlaparoascopy (Gmicrol) and 21 through minilaparotomy (Gminil). Methods: the analyzed parameters were: total time for accomplishment of the procedure and the surgical technique, time of hospital stay and return to the habitual activities after the surgery, postoperative pain, morbidity, satisfaction degree and esthetic effect, considering values of p<0,05 as significant, and also standard cost. Results: Gmicrol took less time to accomplish the surgery than the Gminil (43 against 57 minutes respectively, p<0,05), less time to accomplish the surgical technique (6.48 against 30.32 minutes respectively, p<0,05), and lower hospital stay (9,90 hours as against 41,7 hours respectively, p <0,05). There was no significant difference between the two groups regarding time to return to the habitual activities after surgery. To evaluate postoperative pain, a scale of 0-10 it was applied. Gmicrol present a lower pain score on the 1st and 2nd postoperative days (1.13 and 0.26 to Gmicrol and 4.52 and 1.14 to Gminil, respectively, p<0,05). There was no significant difference between immediate postoperative the most common complaint being pain at the site of pain and that on the 3rd postoperative day. Gminil presented a higher morbidity rate incision. To evaluate the satisfaction degree and esthetic effect, numeric values were attributed to as good, regular, poor and very bad as answered by the patiets. Gmicrol presented a higher satisfaction degree (p<0,05) and better esthetic effect as compared to Gminil (p <0,05). The microlaparoscopy standard cost was R$ 109.30 being lower than that of minilaparotomy. Conclusions: tubal ligation by microlaparoscopy, under local anesthesia and conscious sedation presented some advantages compared to minilaparotomy.

The purpose of the work is to evaluate the stability by dry and humid of theaggregate in different systems or the use and management in Argissolos: agricultural, pasture and torest utilization. This work was realized in agricultural property, in Anhumas city, SR Several analyses including percentage of the aggregate (by way of dry and humid); the weighted mean diameter of the aggregate calculation and statistic analysis. Conclusion: the organic matter content of the A horizon of the soil under forest is 64 % more than the soil under pasture and 79 % more than the soil under annual crop; the WMDA of the aggregate obtained by dry and humid ways of the horizon A and its mean value for the soil decrease in the following sequence: PVAd - forest > PVe -pasture > PVd - annual culture, respectively, with the following values: 1.33560 and 1.445496 (D), 2.81114 and 2.351380 (H); 0.66748 and 1.011830 (D); 2.79642 and 1.624250 (H); 0.32468 and 0.993775 (S), 1.25808 and 0.983135 mm (H); the two methods are equally sensitive to reveal the effect of the soil use and management; the organic matter provides additional stability to the aggregates submitted to humid sieving and clay to the dry sieving: the WMDA obtained by dry and humid ways are statistically different for the soil profiles.

During the first decade of the new millennium, fueled by the economic development in Spain, urban bus services were extended. Since the years 2008 and 2009, the root of the economic crisis, the improvement of these services is at risk due to economic problems. In this paper, the technical efficiency of the main urban bus companies in Spain during the 2004–2009 period are studied using SBM (slack-based measures) models and by establishing the slacks in the services' production inputs. The influence of a series of exogenous variables on the operation of the different services is also analyzed. It is concluded that only the 24% of the case studies are efficient, and some urban form variables can explain part of the inefficiency. The methodology used allows studying the inefficiency in a disaggregated way that other DEA (data envelopment analysis) models do not.

A persistência bacteriana correlacionada à formação de biofilmes bacterianos é, há algum tempo, fonte de grande preocupação médica em virtude de sua ampla associação com a dificuldade de tratamento de infecções crônicas. Por outro lado, as perspectivas de utilização de biofilmes bacterianos em novas aplicações biotecnológicas e até mesmo para fins terapêuticos são promissoras. Há, portanto, grande interesse em compreender os mecanismos que levam as células bacterianas a deixar o estado planctônico, de vida livre, e associarem-se nesses conglomerados celulares altamente complexos. Ao longo das últimas décadas, o segundo mensageiro c-di-GMP – em conjunto com as moléculas que catalisam sua síntese (diguanilato ciclases) e sua degradação (fosfodiesterases) e seus receptores – estabeleceu-se como um elemento central de regulação de uma série de respostas celulares que determinam a formação ou a dispersão de biofilmes. Curiosamente, as proteínas que participam do metabolismo deste segundo mensageiro estão, frequentemente, codificadas múltiplas vezes em um mesmo genoma bacteriano. Em vista dessa observação, estudos mais recentes apontam que, para reger paralelamente uma variedade tão ampla de fenótipos, este sistema opera em modo de alta especificidade de sinalização e que, portanto, o sinal metabolizado por determinados conjuntos de diguanilato ciclases e fosfodiesterases tem alvos celulares específicos. Evidências robustas, porém isoladas até o momento, apontaram que um dos meios pelo qual ocorre a segregação entre sinal produzido e alvo específico é a interação direta entre as proteínas componentes das vias de sinalização. Mais, demonstrou-se que, em algumas vias, a transmissão de sinal ocorre exclusivamente via interação proteica, dispensando a intermediação do sinalizador em si. Para avaliar a validade e relevância global deste mecanismo, propôs-se, neste estudo, a investigação da rede total de interações entre as proteínas tipicamente associadas às vias de sinalização por c-di-GMP em Pseudomonas aeruginosa, utilizando ensaios de duplo-hibrido bacteriano. Para tanto, foram construídas duas bibliotecas de DNA direcionadas e foram feitos testes de interação de forma estratégica para possibilitar o esgotamento e averiguação de todas as possíveis interações entre as proteínas alvo identificadas. O resultado obtido, um mapa inicial, porém abrangente, da rede de interações proteicas em P. aeruginosa, indica uma grande probabilidade de que os mecanismos previamente descritos sejam realmente recorrentes e relevantes para o intermédio da sinalização nesse organismo. Algumas das interações mais robustas encontradas são bastante interessantes e serão, em estudos futuros, mais extensivamente estudadas.
