Communication for Peaceful Social Change and Global Citizenry
The adoption of the 17 Sustainable Development Goals (SDGs) by the United Nations (UN) in 2015
represents a universal call to action involving multiple international actors for the purpose of eradicating
poverty, improving living conditions and promoting peace. This entry provides a theoretical overview of
the contributions of scholars and practitioners who highlight the importance of a transformative,
educational and emancipatory communication by different social actors to establish the main lines of
action for the 2030 Agenda for Sustainable Development. This communicative model involves the
coordination of actors and strategies, both short- and long-term, cross-cutting actions and discourses to
build social, cultural and political settings based on the criteria of peace, equality, social justice and
human rights. Specifically, this entails a contribution to the objectives set out in SDG 16, âPeace, Justice
and Strong Institutionsâ, given that the proposed theoretical framework is grounded in Communication for
Peace and Communication for Social Change, and includes a systematization of different strategies and
experiences from a variety of social issuers, mainly institutions, non-governmental organizations (NGOs)
or social movements, aimed at promoting peaceful and inclusive societies. Specifically, communication
for peaceful social change and global citizenry contributes to the achievement of specific SDG 16
objectives, particularly 16.1: Significantly reduce all forms of violence... [...

âClickâ and Olefin Metathesis Chemistry in Water at Room Temperature Enabled by Biodegradable Micelles
The two laboratory reactions focus on teaching several concepts associated with green chemistry. Each uses a commercial, nontoxic, and biodegradable surfactant, TPGS-750-M, to promote organic reactions within the lipophilic cores of nanoscale micelles in water. These experiments are based on work by K. Barry Sharpless (an azideâalkyne âclickâ reaction) and Robert Grubbs (an olefin cross-metathesis reaction); both are suitable for an undergraduate organic laboratory. The copper-catalyzed azideâalkyne [3 + 2] cycloaddition of benzyl azide and 4-tolylacetylene is very rapid: the triazole product is readily isolated by filtration and is characterized by thin-layer chromatography and melting point analysis. The ruthenium-catalyzed olefin cross-metathesis reaction of benzyl acrylate with 1-hexene is readily monitored by thin-layer chromatography and gas chromatography. The metathesis experiment comparatively evaluates the efficacy of a TPGS-750-M/water medium relative to a traditional reaction performed in dichloromethane (a common solvent used for olefin metathesis)
