Abstract
Purpose
Nonprofit organizations (NPOs) are increasingly using social media outlets to target millennials for donations of time and money. This study aims to investigate the motivational drivers of millennials’ intention to donate money to charities on social media sites (SMSs).
Design/methodology/approach
A partial least squares-structural equation modeling (PLS-SEM) method was used to test the proposed model.
Findings
The results indicate that both information seeking and entertainment, coupled with subjective norm, directly affect millennials’ intention to donate money to NPOs via SMSs. In addition, attitude toward engagement with NPOs on SMSs mediates the impact of credibility (fully, positively), irritation (fully, negatively) and entertainment (partially, positively) on behavior intention. Implications for practitioners are discussed.
Originality/value
An integration of two leading theories, Uses and An integration of two leading theories, Uses and Gratifications (U&G) and the Technology Acceptance Model (TAM)—is used to examine the antecedents of donation behavior of this cohort as related to their engagement with NPOs on SMSs. Such an approach has not been used in the past to examine Millennials’ engagement with NPOs on SMSs.

Abstract
Purpose
This study aims to investigate the inhibition performance of an aqueous extract of Matricaria recutita chamomile on the corrosion of S235JR steel in 0.5 M NaCl by using electrochemical impedance spectroscopy (EIS) and polarization measurements.
Design/methodology/approach
The inhibition performance was investigated using EIS and polarization measurements. Surface analysis demonstrates the presence of a protective layer on the steel surface in the presence of the extract. Quantum chemical parameters calculated for the molecules contained in the aqueous extract are interpreted to predict the corrosion inhibition efficiency of the considered extract.
Findings
The inhibition efficiency of chamomile aqueous extract for S235JR steel increases with increasing amounts of plant concentration and with an increase in the immersion time. The optimal inhibition efficiency of chamomile extract, 98.90 per cent, was achieved for S235JR steel when immersed in 15 per cent v/v of extract concentration for 2 h. The surface analysis in the absence and presence of the chamomile extract confirmed the formation of a protective layer on steel surface. The quantum chemical calculations allowed to explain the great inhibition efficiency values by interpreting the calculated quantum parameters.
Originality/value
This is the first study carrying out an experimental and theoretical investigation on M. recutita chamomile as a green corrosion inhibitor, with interesting potential industrial applications.
