Greenwashing and environmental communication: Effects on stakeholders' perceptions

Since the first Earth Day in the 1970s, corporate environmental performance has increased dramatically, and cases of greenwashing have increased sharply. The term greenwash refers to a variety of different misleading communications that aim to form overly positive beliefs among stakeholders about a company's environmental practices. The growing number of corporate social responsibility claims, whether founded or not, creates difficulties for stakeholders in distinguishing between truly positive business performance and companies that only appear to embrace a model of sustainable development. In this context, through the lens of legitimacy and signalling theory, we intend to understand and assess the different influences that various types of misleading communications about environmental issues have on stakeholders' perceptions of corporate environmental responsibility and greenwashing. Stakeholder responses to an environmental scandal will also be assessed. The hypotheses tested through a four‐for‐two design experiment reveal that different levels of greenwashing have a significantly different influence on stakeholders' perceptions of corporate environmental responsibility and stakeholders' reactions to environmental scandals.     

Value instantiation: how to overcome the value conflict in promoting luxury brands with CSR initiatives

Marketing Letters - When luxury brands (exuding self-enhancement values) incorporate CSR (eliciting self-transcendence values) in their brand platform, they are blending opposing values into their...     

An empirical analysis of ‘acting white’

Using a newly available data set, which allows one to construct a novel measure of a student's social status, we demonstrate that there are potentially important racial differences in the relationship between social status and academic achievement. The effect is concentrated among students with a grade point average (GPA) of 3.5 or higher and more pronounced in schools with more interracial contact. Earlier studies showing a positive relationship between popularity and academic achievement for blacks are sensitive to the inclusion of more continuous achievement measures. We argue that the data are most consistent with a model of ‘acting white’ in which investments in education are taken as a signal of one's opportunity costs of peer-group loyalty, though imprecise estimates make definitive conclusions difficult.     

Alcune proprietà strutturali delle reti di Petri

Dopo aver richiamato i concetti fondamentali sulle reti di Petri, si espongono alcune considerazioni sul problema della raggiungibilità ambientato nello spazio delle transizioni. Si introducono quindi alcune nozioni sulla stabilità e limitatezza strutturali delle reti di Petri, che vengono illustrate con un'applicazione a reti di divisori di frequenza binari. Il problema di decidere della stabilità o limitatezza di una rete di Petri è ricondotto a un problema di programmazione lineare.

After recalling the basic concepts about Petri nets, we consider some aspects of the reachability problem in transition space. In particular, some theorems are given on the markings which enable given firing sequences.The new concept of stability of a Petri net is then introduced and we show that it is possible to decide efficiently if a net is stable or bounded by solving a unique linear programming problem.An application to binary frequency divisors is given last.
