Creating value through communication

Communication can play a significant role in the value creation process of the organisation, considering the fact that the value of the capitals produced by the organisation can increase and decrease depending on what the organisation says and does. Integrating the corporate communication process into the strategic management, governance and value creation processes therefore pose an opportunity for communication professionals to illustrate how communication can contribute to the creation of value for organisations, and as such be of benefit to business and to society. Introducing these communication approaches to value creation in the organisation requires a new responsible, integrative perspective on the role of corporate communication.     

The use of bodies. Agamben’s idea of a non-capitalist form of life

Abstract

With the notion of the form-of-life as a counter-figure to the notion of bare life, Agamben seems to invite us to place at the center of a critical theory of capitalism a reflection on bios. To envisage a form of emancipation that unfolds against bare life suggests, at first glance, another relation to the living body. Such a gesture seems to be inspired by the desire to think a natural life that would also be a politically qualified life. The idea with which Agamben closes the Homo Sacer series, namely that of a use of bodies, also gestures in this direction. In this paper I show how the categories of bare life and of the use of bodies fail to live up to their promise, before demonstrating in what sense the idea of a subtraction of law as a political project which subsumes all others ends up weakening the critical potential of the idea of a form-of-life that is to be realised against the force of production of bare lives.     

Longitudinal Change in Adolescent Depression and Anxiety Symptoms from before to during the COVID-19 Pandemic

This study aimed to examine changes in depression and anxiety symptoms from before to during the first 6 months of the COVID-19 pandemic in a sample of 1,339 adolescents (9–18 years old, 59% female) from three countries. We also examined if age, race/ethnicity, disease burden, or strictness of government restrictions moderated change in symptoms. Data from 12 longitudinal studies (10 U.S., 1 Netherlands, 1 Peru) were combined. Linear mixed effect models showed that depression, but not anxiety, symptoms increased significantly (median increase = 28%). The most negative mental health impacts were reported by multiracial adolescents and those under ‘lockdown’ restrictions. Policy makers need to consider these impacts by investing in ways to support adolescents’ mental health during the pandemic.
