We studied an interactive (functional and intentional interactivity) and immersive (technical and psychological immersion) device with a personal 3D viewer (360° vision and environmentally ego-centered) and its effects on the explicit long-term memories of the subjects (4 groups of 30 students for a total of 120 subjects) (2007 and 2012).We have tested memory, communication and feeling of presence in our virtual environment with a canonic test of presence (Witmer and Singer, 1998). This article is a reflection on these 3D devices and their impact on the long term memory of the students, and on their presence sensation. © 2014 Springer International Publishing. Source

A frequent criticism of eco-efficiency strategies is that an increase in efficiency can be offset by the rebound effect. Sufficiency is discussed as a new strategy involving self-imposed restriction of consumption but can also be subject to the rebound effect. We show that the range of possible secondary effects of efficiency and sufficiency strategies goes beyond the rebound effect. The rebound effect can indeed also be linked to eco-sufficiency strategies but there are further secondary effects of both eco-efficiency and eco-sufficiency strategies, such as double dividend effects. We develop an 'Eco-efficiency- sufficiency matrix' to logically order eco-efficiency and sufficiency measures to attain lower resource consumption and emissions. © 2014 Elsevier Ltd.

We analyze the suitability of cross-sector partnerships as an effective mechanism for private environmental governance. By focusing on the interaction between firms within cross-sector partnerships, we analyze how competition between firms affects partnership effectiveness. Marrying insights from the private governance literature with institutional theory and the resource-based view, we identify under which conditions firm-level competition for legitimacy and capabilities, respectively, undermines or enhances effectiveness of cross-sector partnerships to address environmental issues. In doing so, our argument develops the various factors that moderate the relationship between competition and effectiveness for different types of partnerships. We contend that the effectiveness of cross-sector partnerships for governing global environmental issues depends considerably on whether competitive forces at the firm level are aligned with the collective benefits of partnerships. We discuss the consequences for designing effective cross-sector partnerships as well as the implications of a firm perspective on private governance. © 2014 SAGE Publications. Source

The study details why and how product reviews from consumer opinion platforms affect individual users' brand buying behavior. Drawing on social theories, the authors predict that consumers' perceptions of other consumers' product reviews affect brand buying intentions through two intervening variables: product- and brand-related attitudes. Moreover, the authors investigate whether these relationships are contingent on user type (i.e., active posters or passive lurkers). The empirical results support a multiple mediation framework in which product- and brand attitudes mediate the effects of consumer product reviews on individual brand buying intentions. In addition, consumer product reviews appear to more strongly affect the brand-related attitudes of posters than lurkers. Lurkers, who make up the majority of opinion platform users, are much less influenced by the opinions of others than posters. Encouraging variations in poster- and lurker rates may be an effective means for companies to manage and control consumer-to-consumer communication. © 2014 Institute of Information Management, University of St. Gallen.

There are many studies on container port efficiency and that seek to understand what factors, such as technical and scale efficiency, private versus public terminal management or macro-economic factors, play on the efficiency score of a given port. There are fewer studies that focus on the role played by the inter-port competitive environment. This role remains difficult to assess. In fact, on the one hand, a port subject to high inter-port competition may record higher efficiency scores due to the pressure from the competitive environment. On the other hand, a port subject to high competition may be forced to over-invest and could therefore records a lower efficiency score. This article investigates this issue and examines how the degree of competition measured at different levels (local, regional and global level) impacts the efficiency score of a given container port. To do so, we implement a truncated regression with a parametric bootstrapping model. The model applied to information gathered for 200 container ports in 2007 and 2010 leads to the following conclusions: port efficiency decreases with competition intensity when measured in a range of 400-800. km (regional level); and the effect from competition is not significant when competition is measured at a local (less than 300. km) or at a global (more than 800. km) level. Estimates also show a tendency for ports who invested from 2007 to 2010 to experience a general decrease in efficiency scores, an element which could be explained by the time lag between the investment and the subsequent potential increase in container throughput. © 2015 Elsevier Ltd.
