This paper analyses the pre-professional journalistic culture of Ecuador, Cuba and Venezuela based on the degree of permissiveness held by Journalism students in regard to controversial ethical practices and their views of the media and the journalistic profession. We surveyed a probabilistic sample of 1,273 students from 21 universities enrolled on their first course (Ecuador=500, Venezuela=390, Cuba=383) in 2016. The results show that future journalists are reluctant to accept questionable journalistic practices, and hold a pessimistic view as to the quality and confidence of the media and the profession. We found that the degree of permissiveness is related to the perceived risk-reward analysis in terms of the quality of journalism in Cuba and Ecuador, and that the student perceptions of ethics differ in Venezuela and Ecuador. We conclude that, despite their political similarities in terms of having left-wing Governments, perceptions in the three countries diverge. [ABSTRACT FROM AUTHOR]

The large-scale analysis of tweets in real-time using supervised sentiment analysis depicts a unique opportunity for communication and audience research. Bringing together machine learning and streaming analytics approaches in a distributed environment might help scholars to obtain valuable data from Twitter in order to immediately classify messages depending on the context with no restrictions of time or storage, empowering cross-sectional, longitudinal and experimental designs with new inputs. Even when communication and audience researchers begin to use computational methods, most of them remain unfamiliar with distributed technologies to face big data challenges. This paper describes the implementation of parallelized machine learning methods in Apache Spark to predict sentiments in real-time tweets and explains how this process can be scaled up using academic or commercial distributed computing when personal computers do not support computations and storage. We discuss the limitation of these methods and their implications in communication, audience and media studies. [ABSTRACT FROM AUTHOR]

This paper describes the rate of adoption, frequency and uses of Social Media by young people in the Caribbean Region of Colombia. We report a crosssectional survey of 502 youngsters (16 to 28 years) enrolled to the National Learning Service or Servicio Nacional de Aprendizaje (SENA). Findings show that the average adoption rate of Social Media was 68 %, being the most frequently used Facebook (69.4 %), Google+ (57.6 %), Instagram (45.6 %) and Twitter (42.6 %). Data revealed that the main uses of Social Media by young Colombians were to read news stories, followed by connecting with friends and relatives, and finding music and videos. This is the first study in Colombia with youngsters belonging to low-income families but with frequent access to Internet, which contributes to understand the importance of Social Media in this vulnerable group. Our findings might also help to identify useful possibilities of new media for young people. Finally, we discuss practical implications of the results. [ABSTRACT FROM AUTHOR]

e-Research into communications in Venezuela Information and communication technologies have changed the way researchers approach their studies: new tools and methods that overcome the barriers of distance and time enable them to build wide-ranging collaborations at national and international levels, as well as to manage vast amounts of data. The intensive use of these digital tools has come to be known as e-Research. Scholars view e-Research positively, but they demand for greater training in the tools and methods. Studies also reveal a significant gap between the advanced state of e-Research in the natural sciences and lower levels of adoption in the social sciences, as well as showing a gap between regions and countries in terms of available resources for the development of e-Research. This paper analyses the current state of e-Research into communications in Venezuela, its advances and trends and how it differs when compared to the situation internationally, regionally and in respect of other disciplines - from the literature review to the interviews with leading communications researchers.

The objective of this paper is to explore the main results of the project "Participation and social relationships in Twitter's online opinion leaders in Colombia, Venezuela and Iran, linked to the authors' research field. Our initial hypothesis said that new social networks in online media are strengthening the application of the flow communication model proposed by Klaus Jensen (Three-Step Flow), as well as they are contributing to the emergency of new opinion leaders. The findings confirm the relevance of Jensen's model and show how, the formation of new leaders of opinion online depend of factors out the ICT's effect. [ABSTRACT FROM AUTHOR]
