By its experience, we address convergence on journalism, through two main discussions: media convergence in the same journalistic publication, and editorial convergence, treated here as a mixture of popular and quality press. For that, we combine theoretical perspectives from culturalism and from Cultural Studies to problematize questions from the convergence culture (JENKINS, 2009), using the perspective of technology as effect (WILLIAMS, 2005) and the media language in the sphere of mediations (MART?N-BARBERO). The complexity of the comprised questions was addressed through an analysis of the product itself, qualitative interviews and the investigation of spontaneous comments about The Daily on the App Store. According to what was researched, it is proposed the configuration of a hybrid journalism in a convergent medium, perhaps in a context where the dichotomous classification between popular and quality press doesn t make sense anymore in a landscape of hybrid cultures (CANCLINI, 2003). Furthermore, we perceive that the media convergence of The Daily is still in an experimental, transitional sphere, without completeness. With the appearance of mobile technologies, digital journalism also started to aggregate mobility, bringing peculiarities and issues that may form even a new phase of digital journalism. The Daily has ceased its activities on December 15th and brought contributions to the study of convergence in journalism.O The Daily foi a primeira publica??o de seu tipo exclusiva para tablets, e se parte dele para tratar da converg?ncia no jornalismo, atrav?s de duas problematiza??es principais: a converg?ncia de linguagens em uma mesma publica??o jornal?stica e a converg?ncia editorial, tratada aqui como uma mistura de elementos do jornalismo popular e de refer?ncia. Para tanto, colocam-se em di?logo perspectivas te?ricas do culturalismo e dos Estudos Culturais a fim de problematizar as quest?es da cultura da converg?ncia (JENKINS, 2009), atrav?s de uma perspectiva das tecnologias como efeito (WILLIAMS, 2005) e dos suportes no ?mbito das media??es (MART?N-BARBERO, 2009b). A complexidade das quest?es abarcadas foi trabalhada atrav?s da an?lise de produto, de entrevistas qualitativas e de coment?rios espont?neos sobre o The Daily na loja de aplicativos. Frente ?s an?lises, prop?e-se a configura??o de um jornalismo h?brido em um meio convergente midiaticamente; talvez um contexto em que a classifica??o dicot?mica entre jornalismo popular e de refer?ncia n?o fa?a mais sentido em um cen?rio de culturas h?bridas (CANCLINI, 2003). Al?m disso, percebe-se que a converg?ncia midi?tica no The Daily ainda figura em ?mbito experimental, de transi??o, sem completude. Com o surgimento das tecnologias m?veis, o jornalismo digital passou a ter a mobilidade agregada a ele, trazendo peculiaridades e quest?es que talvez se configurem em uma nova fase do jornalismo digital. O The Daily encerrou as atividades em 15 de dezembro de 2012 e trouxe contribui??es para a an?lise da converg?ncia no jornalismo

Immunotherapy against experimental canine visceral leishmaniasis with the saponin enriched-Leishmune ? vaccine.

In order to assess the immunotherapeutic potential on canine visceral leishmaniasis of the Leishmune ? vaccine, formulated with an increased adjuvant concentration (1 mg of saponin rather than 0.5 mg), 24 mongrel dogs were infected with Leishmania (L.) chagasi . The enriched-Leishmune ? vaccine was injected on month 6, 7 and 8 after infection, when animals were seropositive and symptomatic. The control group were injected with a saline solution. Leishmune ? -treated dogs showed significantly higher levels of anti-FML IgG antibodies (ANOVA; p < 0.0001), a higher and stable IgG2 and a decreasing IgG1 response, pointing to a TH1 T cell mediated response. The vaccine had the following effects: it led to more positive delayed type hypersensitivity reactions against Leishmania lysate in vaccinated dogs (75%) than in controls (50%), to a decreased average of CD4+ Leishmania -specific lymphocytes in saline controls (32.13%) that fell outside the 95% confidence interval of the vaccinees (41.62%, CI95% 43.93?49.80) and an increased average of the clinical scores from the saline controls (17.83) that falls outside the 95% confidence interval for the Leishmune ? immunotherapy-treated dogs (15.75, CI95% 13.97?17.53). All dogs that received the vaccine were clustered, and showed lower clinical scores and normal CD4+ counts, whereas 42% of the untreated dogs showed very diminished CD4+ and higher clinical score. The increase in clinical signs of the saline treated group was correlated with an increase in anti-FML antibodies (p < 0.0001), the parasitological evidence ( p = 0.038) and a decrease inLeishmania -specific CD4+ lymphocyte proportions (p = 0.035). These results confirm the immunotherapeutic potential of the enriched-Leishmune ? vaccine. The vaccine reduced the clinical symptoms and evidence of parasite, modulating the outcome of the infection and the dog?s potential infectiosity to phlebotomines. The enriched-Leishmune ? vaccine was subjected to a safety analysis and found to be well tolerated and saf

Quantifying Preferences for the Natural World Using Monetary and Nonmonetary Assessments of Value.

Given that funds for biodiversity conservation are limited, there is a need to understand people's preferences for its different components. To date, such preferences have largely been measured in monetary terms. However, how people value biodiversity may differ from economic theory, and there is little consensus over whether monetary metrics are always appropriate or the degree to which other methods offer alternative and complementary perspectives on value. We used a choice experiment to compare monetary amounts recreational visitors to urban green spaces were willing to pay for biodiversity enhancement (increases in species richness for birds, plants, and aquatic macroinvertebrates) with self-reported psychological gains in well-being derived from visiting the same sites. Willingness-to-pay (WTP) estimates were significant and positive, and respondents reported high gains in well-being across 3 axes derived from environmental psychology theories (reflection, attachment, continuity with past). The 2 metrics were broadly congruent. Participants with above-median self-reported well-being scores were willing to pay significantly higher amounts for enhancing species richness than those with below-median scores, regardless of taxon. The socio-economic and demographic background of participants played little role in determining either their well-being or the probability of choosing a paying option within the choice experiment. Site-level environmental characteristics were only somewhat related to WTP, but showed strong associations with self-reported well-being. Both approaches are likely to reflect a combination of the environmental properties of a site and unobserved individual preference heterogeneity for the natural world. Our results suggest that either metric will deliver mutually consistent results in an assessment of environmental preferences, although which approach is preferable depends on why one wishes to measure values for the natural world.
