Project Evaluation: A Mixed-Method Study into Dilemmas in Continuation Decisions

Project evaluations are highly crucial for organizations to manage their information systems and technology project portfolios. This study postulates equivocal situations as the source of dilemmas hindering stakeholders to achieve proper evaluation and purposeful decisions. We examine three factors that are conceived to have high association with equivocal situations when evaluating IS/IT projects, Challenges in project management, Different frames of reference and Lack of evaluation data. The developed model is tested using a survey data of IS/IT professionals through PLS. We find the three factors are significantly affecting the occurrence of equivocal situations with the highest contribution come from the Challenges in project management. Multi-group examinations reveal distinct impacts of the three factors within public versus private sector and high versus low projects in the project evaluation ladder. Post hoc interviews suggest several interesting points especially on how to cope with equivocal situation

Accelerated Dissipation of the Herbicide Cycloxydim on Wax Films in the Presence of the Fungicide Chlorothalonil and under the Action of Solar Light.

International audiencePhotolysis is a known dissipation pathway of pesticides on leaves just after their spraying. This pathway may be affected by the residues of other pesticides. To illustrate this idea, this study investigated the mutual effect of two pesticides (chlorothalonil and cycloxydim) under simulated solar light. Cycloxydim was added at the agricultural rate (200 g ha–1) and chlorothalonil at 1.3–10% of the rate (20–150 g ha–1). These compounds were studied either pure or in their commercial formulation. Both analytical and kinetic data show that chlorothalonil significantly accelerates the decay of cycloxydim on wax films, promoting its oxidation, even at the lowest tested dose. Conversely, cycloxydim does not affect the fate of chlorothalonil. Moreover, the detection of oxidized forms of wax alkanes in the extracts demonstrates that chlorothalonil may have also a degrading effect on the leaves’ constituents under the action of solar light

Using communities of practice theory to teach Public Relations in higher education: a case study of an international undergraduate course

This paper introduces and empirically illustrates a pedagogical approach to teaching Public Relations (PR) in higher education. The approach is based on the Communities of Practice theory (Wenger, 1998). Based on this theory and for the purposes of this paper, learning is perceived as (1) a participation in a practice of (2) a social community and (3) the understanding of this practice. The pedagogical approach to teaching PR entails the facilitation of these three elements. The approach is illustrated through a case study. The authors conducted an international undergraduate course to teach students how to conduct a social media campaign to raise engagement for social issues. Twenty students from Netherlands and Germany enrolled. The paper offers an integrated understanding of theory and practice (see Wenger, 1998, p. 48). It contrasts many current approaches in PR education, which tend to differentiate between PR theory and practice. PR educators are encouraged to facilitate an equal negotiation between theory and practice and to enable students to match whatever is theorised with practice and whatever is practiced with theory
