Empoderamiento de los jóvenes a través de las redes sociales. Construcción de una ciudadanía digital comprometida

La búsqueda de la implicación y la participación ciudadana en el desarrollo de un sistema social no es un fenómeno nuevo o que haya surgido con la comunicación digital. Sin embargo, las redes sociales y los entornos virtuales están transformando el modo en el que los individuos, y especialmente los jóvenes, se sienten llamados a la acción. La investigación cuantitativa mediante encuestas que se presenta aquí analiza cómo los jóvenes emplean herramientas online y offline para dar a conocer y apoyar las “causas 2.0”. La comunicación digital puede facilitar la cooperación y solidaridad ante determinadas iniciativas sociales que demandan esa movilización activa. Sin embargo, esa ventaja competitiva que puede ofrecer la tecnología se encuentra influenciada por múltiples variables (empatía, proximidad, identificación con la causa…). Resulta imprescindible saber qué es lo que quieren los jóvenes y cuál es el modo de captar su atención para lograr ese compromiso social. Los resultados de este trabajo parecen indicar que lo que moviliza a los jóvenes a la hora de participar en alguna acción solidaria son los aspectos puramente racionales y emocionales, dejando más de lado la propia creatividad de la campaña, la organización que impulsa la acción o la presencia de prescriptores famosos o influenciadores. Prefieren la esencia de las propias acciones sociales.Ensuring citizen involvement and participation in the development of a social system is not a new phenomenon, nor has it emerged with digital communication. However, social networks and virtual environments are transforming the way in which individuals, especially young people, are called to action. This quantitative research paper analyzes how young people use online and offline tools to publicize and support "2.0 causes". Digital communication can facilitate cooperation and solidarity toward certain social initiatives that require active mobilization. However, the competitive advantage that technology can offer is greatly influenced by numerous variables (empathy, closeness, identification with the cause, etc.). It is essential to become familiar with the desires of young people and to find the best ways to gain their attention in order to help them achieve their goals of social commitment. The results of this research suggest that the factors mobilizing young people when they participate in solidarity movements are purely rational and emotional, with less emphasis being placed on the creativity of the campaign, the organization that promotes the action, or the presence of famous prescribers or influencers. They prefer the essential qualities of social activism in itself

Dietary α‐Linolenic Acid, Marine ω‐3 Fatty Acids, and Mortality in a Population With High Fish Consumption: Findings From the PREvención con DIeta MEDiterránea (PREDIMED) Study

Background: Epidemiological evidence suggests a cardioprotective role of α‐linolenic acid (ALA), a plant‐derived ω‐3 fatty acid. It is unclear whether ALA is beneficial in a background of high marine ω‐3 fatty acids (long‐chain n‐3 polyunsaturated fatty acids) intake. In persons at high cardiovascular risk from Spain, a country in which fish consumption is customarily high, we investigated whether meeting the International Society for the Study of Fatty Acids and Lipids recommendation for dietary ALA (0.7% of total energy) at baseline was related to all‐cause and cardiovascular disease mortality. We also examined the effect of meeting the society's recommendation for long‐chain n‐3 polyunsaturated fatty acids (≥500 mg/day). Methods and Results: We longitudinally evaluated 7202 participants in the PREvención con DIeta MEDiterránea (PREDIMED) trial. Multivariable‐adjusted Cox regression models were fitted to estimate hazard ratios. ALA intake correlated to walnut consumption (r=0.94). During a 5.9‐y follow‐up, 431 deaths occurred (104 cardiovascular disease, 55 coronary heart disease, 32 sudden cardiac death, 25 stroke). The hazard ratios for meeting ALA recommendation (n=1615, 22.4%) were 0.72 (95% CI 0.56–0.92) for all‐cause mortality and 0.95 (95% CI 0.58–1.57) for fatal cardiovascular disease. The hazard ratios for meeting the recommendation for long‐chain n‐3 polyunsaturated fatty acids (n=5452, 75.7%) were 0.84 (95% CI 0.67–1.05) for all‐cause mortality, 0.61 (95% CI 0.39–0.96) for fatal cardiovascular disease, 0.54 (95% CI 0.29–0.99) for fatal coronary heart disease, and 0.49 (95% CI 0.22–1.01) for sudden cardiac death. The highest reduction in all‐cause mortality occurred in participants meeting both recommendations (hazard ratio 0.63 [95% CI 0.45–0.87]). Conclusions: In participants without prior cardiovascular disease and high fish consumption, dietary ALA, supplied mainly by walnuts and olive oil, relates inversely to all‐cause mortality, whereas protection from cardiac mortality is limited to fish‐derived long‐chain n‐3 polyunsaturated fatty acids.
