Flotar en la viscosidad. Literatura cubana de los 90

Flotar en la viscosidad. Literatura cubana de los 90, is a dissertation that focuses on Cuban literature in the 90s as one of the stages of major changes and literary projections after 1959 in Cuba, as part of Latin American literary developments following the collapse of the Berlin Wall. The late twentieth century in Cuba was a time of fractures and vulnerabilities in different representations of the social subject and his/her circumstances, historically manipulated by the government. As examples of this rupture with the socialist literary canon, I study three authors and their representative works from this period: the poet Reina María Rodríguez, the narrator Pedro Juan Gutiérrez and the poet, narrator and essayist Antonio José Ponte. As I demonstrate in my thesis, their works are able to dialogue with particular and dissimilar voices using original prose fiction, poetry and essayistic elements, mostly absent on the island map during three decades of socialism. Similarly, their books reflect a critical period, damaged paradigms and a new subject that coincides with a novel national imaginary, contrasting with the new man (“el hombre nuevo”) as symbol of the socialist regime. In this regard, I have paid close attention to two major events for the continent after the collapse of the Berlin Wall: the so-called “special period in peace time” and the triumph of neoliberal globalization in the rest of Latin America

Development and implementation of a potential coronavirus disease 2019 (COVID-19) vaccine: A systematic review and meta-analysis of vaccine clinical trials.

Background: To date, there is no comprehensive systematic review and meta-analysis to assess the suitability of COVID-19 vaccines for mass immunization. The current systematic review and meta-analysis was conducted to evaluate the safety and immunogenicity of novel COVID-19 vaccine candidates under clinical trial evaluation and present a contemporary update on the development and implementation of a potential vaccines. Methods: For this study PubMed, MEDLINE, and Embase electronic databases were used to search for eligible studies on the interface between novel coronavirus and vaccine design until December 31, 2020. Results: We have included fourteen non-randomized and randomized controlled phase I-III trials. Implementation of a universal vaccination program with proven safety and efficacy through robust clinical evaluation is the long-term goal for preventing COVID-19. The immunization program must be cost-effective for mass production and accessibility. Despite pioneering techniques for the fast-track development of the vaccine in the current global emergency, mass production and availability of an effective COVID-19 vaccine could take some more time. Conclusion: Our findings suggest a revisiting of the reported solicited and unsolicited systemic adverse events for COVID-19 candidate vaccines. Hence, it is alarming to judiciously expose thousands of participants to COVID-19 candidate vaccines at Phase-3 trials that have adverse events and insufficient evidence on safety and effectiveness that necessitates further justification

The societal context of professional practice: Examining the impact of politics and economics on journalistic role performance across 37 countries

The impact of socio-political variables on journalism is an ongoing concern of comparative research on media systems and professional cultures. However, they have rarely been studied systematically across diverse cases, particularly outside Western democracies, and existing studies that compare western and non-western contexts have mainly focused on journalistic role conceptions rather than actual journalistic practice. Using journalistic role performance as a theoretical and methodological framework, this paper overcomes these shortcomings through a content analysis of 148,474 news stories from 365 print, online, TV, and radio outlets in 37 countries. We consider two fundamental system-level variables—liberal democracy and market orientation—testing a series of hypotheses concerning their influence on the interventionist, watchdog, loyal-facilitator, service, infotainment, and civic roles in the news globally. Findings confirm the widely asserted hypothesis that liberal democracy is associated with the performance of public-service oriented roles. Claims that market orientation reinforces critical and civic-oriented journalism show more mixed results and give some support to the argument that there are forms of “market authoritarianism” associated with loyalist journalism. The findings also show that the interventionist and infotainment roles are not significantly associated with the standard measures of political and economic structure, suggesting the need for more research on their varying forms across societies and the kinds of system-level factors that might explain them
