title: Research on social media and journalism (2003-2017): a bibliometric and content review

description: Abstract This paper introduces a bibliometric review of the scientific literature on social media and journalism published by journals indexed by Journal Citation Reports until 2017 (n=213). Besides descriptive measurements, it provides a co-citation and co-word analysis. A quantitative content analysis complements the bibliometric approach. Thus, the paper offers a conceptual and structural analysis of the field of study. Results show that the number of articles on the topic is growing steadily since 2014. United States, Australia and England stand as the most productive countries. Studies are based mostly on data from Europe and North America. Three conceptual clusters are identified: audience participation, user generated content and the influence of social media on journalistic professional values and practices. Most of the studies did not consider specific services but focused on the general concept of “social media”. Twitter was the most analyzed platform until recent years, when scholarly attention changed towards Facebook. Research has preferred focusing on political information in detriment of other branches of journalism. The most employed methods are content analysis and in-depth interviews. Further use of surveys and social network analysis, as well as stronger focus on visual studies, is suggested.

title: Developing an ontology network about meteorological events from historical newspapers

description: Abstract Currently, only a few people would deny the value of newspaper content for understanding issues associated with politics, culture, and society. Therefore, the digitalization of the newspapers’ archives allows retrieving outstanding historical and cultural articles. However, there is a large amount of “minor data” hidden within these newspapers. This paper addresses the challenge for accessing and dealing with the resources of National newspaper and periodicals libraries from Colombia, Ecuador, México and Uruguay, which collect newspapers where news about meteorological events from the XIX-XX centuries were posted. A news corpus is developed on these newspapers, which through technical readings and a bibliomining process using different tools allow building an ontology network. This network is composed of different modules (technical, general and news), which are built using different approaches (top-down and bottom-up) and methodologies (Methontology and NeOn), for providing a common and sharing understanding of the historical meteorological events in Latin America. Hence, this work entails an approach to take the newspaper and periodicals libraries to Semantic Web.

title: Maturation and Desiccation Tolerance in Seeds of Sesbania virgata (Cav.) Pers.

description: ABSTRACT The maturation process of Sesbania virgata seeds was investigated through fruits and seeds at different maturation stages, where they were described morphologically. For the seeds, fresh and dry mass and moisture were determined and structural analysis of the tegument under a light microscope was performed. Germination tests in the presence and absence of drying and the electrophoretic profile of heat resistant proteins were also performed. The results showed that the seeds reached physiological maturity at 44 days after anthesis (DAA), evidencing a secondary cell wall. The acquisition of desiccation tolerance was observed at 44 DAA, with the seeds responding to the drying treatment. Protein bands were observed from 32 DAA, which remained constant until the end of maturation. These results allowed the characterization of the development and acquisition of desiccation tolerance in S. virgata seeds.

title: Floristic and Structural Composition of Natural Regeneration in a Subtropical Atlantic Forest

description: ABSTRACT Understanding the regeneration process in an old growth forest is essential for restoration projects. The present research sought to characterize the floristic and structural composition of shrub-tree species in São Francisco de Assis Municipal Park in Blumenau-SC. We sampled 50 permanent plots divided into three height classes. We estimated the total natural regeneration index for each species, the Shannon-Wiener diversity index and Pielou equability, and classified the species according to life-form and ecological group. A total of 1048 individuals were found, distributed in 112 species, 69 genera and 37 families. The species with the highest values of total natural regeneration index were Rudgea recurva, R. jasminoides, Ouratea parviflora, Psychotria nuda and Virola bicuhyba. The Shannon and Pielou indices demonstrated high diversity and equability for the natural regeneration area sampled. The results indicate species possibly capable of reaching the tree strata, and also indicate high forest conservation.

title: Online transparency as an intangible asset of the public sector

description: Abstract Public organizations must face the management of their intangible assets in different ways. Regarding transparency, the implementation of different specific laws (local and nationwide) which affect the way public information is presented has been a common practice in the case of Spanish public administrations. This study analyses the consequences of the application of such laws by assessing the evolution of the level of transparency presented by local administrations, taking as a case study all Councils in the Region of Murcia. Data collected in three waves (2015, 2016, and 2017) have been included in order to measure the evolution of this intangible asset in a timeline. For the analysis of the online transparency level, 52 indicators were used (tested nationwide). The results show that, five years after the implementation of the law, even though there has been a slight improvement, a generalized deficit in the real implementation of the transparency regulation is still visible, which affects key points related to its intangibility. At the same time, there are significant differences in the degree of compliance depending on the sex of the mayors who were in charge of the municipality.

title: Scientific production in the study of user experience in education: case Web of Science and Scopus

description: Abstract This work has the goal to make an approximation of the evolution and general features present in scientific production disclosed in Web of Science and in Scopus, related to the study of user experience in education. The work analyzes the totality of the production registered in the indexation systems taken as a case of study, 194 records obtained from the use of terms user experience and edoucation. The study carries out a content analysis of the abstract and institutional, editorial and author information exposed in the Web of Science andScopus, in addition to the analysis of the bibliometric indicators of each identified work. Obtained data show that more than 80% of the scientific production around the topic addressed, mostly generated in scientific events, has been produced in the last 5 years, under the authorship and institutional affiliation of academic institutions and publishers from the United States. This would point out to a new academic framework, of growing interest, around the analysis of the user experience from an educational perspective, conditioned bya highly focused debate on a geographical area, which is assuming a prominent role in the first approaches that are emerging on this subject, at the scientific level.

title: Classic and Modern film focalization: information structures in the history of narrative film

description: Abstract In narrative films, viewers extract information about the plot either from reading the characters’ mental states or through assumptions about the intentions of the implicit author of the work. This reading can be supported by inferences about the subjects’ behaviours or through the representations of the characters’ stream of consciousness. This text examines the relationship between the mentioned variable of the mental state and the filmic style – Classic or Modern. It uses the Internet Movie Data Base, pointing to concepts that refer to the subjective construction of a character’s consciousness stream, such as Voice Over, Point-of-view hot, or Flashback. The results and their methodological limitations are framed within theoretical debates about the Focalization and Information Structure of a fiction plot. Classic Cinema uses behaviour to infer the characters’ mental states, while Modern Cinema considers the possibility of audio-visual representation for such streams of consciousness. The “objective” discourse of “zero focalization” best fits the inferences about behaviour employed in Classic Cinema, while Modern Cinema adapts to the subjectivity expressed by “internal focalization”. As further investigation, it would be convenient to discover the relationship between the styles of Cinema, Classic or Modern, and their potential to develop the theory of mind.

title: GYPSUM AND PHOSPHORUS IN IMPROVING BIOMETRIC AND NUTRITIONAL ATTRIBUTES OF SOYBEAN/SECOND SEASON CORN SUCCESSION

description: ABSTRACT The objective with this work was to evaluate the effect of the agricultural gypsum, associated with phosphate fertilization, on the nutrition, development and yield of soybean and corn in succession, under no-tillage system. The experiment was conducted at Universidade Federal de Goiás, Regional Jataí, in a randomized blocks design 5x3 factorial arrangement, with 4 replicates. The first factor consisted of the gypsum doses (0, 1, 2, 4 and 8 Mg ha-1) and the second the phosphorus doses (0, 50 and 100% of the recommended dose). Leaf nutrient contents, leaf area index, SPAD index, dry plant mass, final plant population, one thousand grain mass and grain yield were evaluated in the crops. In the soybean, the number of pods was also obtained and in the corn the average ear length, number of rows per ear, number of grain per ear and number of ears. Phosphorus doses increase leaf Mg contents in soybean and corn. The application of gypsum reduces the Mg and K leaf contents and increases the Ca, S, and Mn contents in the two cultures. Gypsum provides increases in the SPAD index in soybean plants. The unbalance of the N / K ratio in corn leaves, provided by the increase of the gypsum doses, reduces the leaf area of this crop. Doses of P and gypsum do not influence the yield of soybeans and maize.

title: Molecular studies on African swine fever virus from Brazilian isolates

description: ABSTRACT: African swine fever (ASF) is a devastating viral infirmity that affects domestic and wild swine caused by the ASF virus (ASFV) that belongs to the family Asfaviridae in the Asfavirus genus. Studies for genotypic and antigenic determination of ASFV including samples from Brazilian outbreaks were carried out outside Brazil. Here, we have reviewed studies on the molecular aspects of Brazilian isolates from 1978 and 1979. Results obtained from restriction fragment analysis, cloning and gene sequencing display the genotypic variation of viral samples. Viral genotyping based on sequences of the 3’ region of the p72 gene included in genotype I Brazilian samples, reinforcing the suggestion of the European origin for the virus that infected Brazilian herds and having low virulence potential. Corroborating those findings, at the American station PIADC, the infection of healthy pigs with the Brazilian strain induced ASF sub acute disease with low mortality and a low-virulence. Those results were similar with epidemiological vigilance forms of Brazilian swineherd in good health conditions having at least one ASFV isolation, and the ASF pioneer’s studies on the low mortality in the Brazilian herds affected by ASF. The ASFV spreading in Eastern Europe and Russia triggered a greater concern with intensifying the risk of viral dissemination from country to country. The low virulence ASF strains can increase the problem because of hidden viral reservoirs - which further reinforces the need for safety and preventive measures in virus-free countries. Finally, the problem is further compounded by the lack of vaccines and other immunological resources.

title: How 'Democratic' is the Democratic Peace? A Survey Experiment of Foreign Policy Preferences in Brazil and China

description: Recent research has shown that British and American respondents are less willing to advocate the use of force against fellow democracies than against non-democracies (TOMZ and WEEKS, 2013). These findings may contribute to understandings of the 'democratic bias'—unwillingness to attack democracies. A critical next step is assessing whether publics beyond the US and the UK have similar attitudes. To address the scope of popular preferences for peace with democracies, we conduct survey experiments using online panels in two emerging powers, one a democracy (Brazil) and one a non-democracy (China). Our survey randomly varies the hypothetical target's regime type and authorization by the United Nations for military action. We find that Brazilian respondents are significantly less likely to support the use of force against a democracy than a non-democracy. However, after controlling for UN approval, Chinese respondents do not appear to distinguish between democracies and non-democracies when considering whether force is justified. In addition, for both countries, UN approval has a larger effect than democracy on public support for the use of force.
