This theoretical-review article contributes to the discussion on individual energy savings by developing a hypothetical classification of interventions and linking them to sociopsychological factors affecting the transition points of four phases of behavior change (predecision, preaction, action, and postaction). It helps to segment a population into subgroups, clarifies the dynamic process for individuals, and groups examples of interventions to achieve substantial behavioral change. The generic integrative model presents © 2017. This manuscript version is made available under the Elsevier user license http://www.elsevier.com/open-access/userlicense/1.0/ 2 academic study designers and practitioners with a theoretical viewpoint and an orientation framework for their intervention designs. A systematic literature review of the empirical evidence for the model and interventions is presented. This blueprint of a model can be adapted, specified, further developed and implemented as a backbone for empiricallygrounded intervention design.

Pre-set options, referred to as default options, have been found to influence consumer choices in various settings. In this paper, we investigate the effect of default options on the chosen categories of board and lodging in travel packages. The results of two field experiments indicate that guests traveling as couples are more likely to book a superior room and additional meals if the high-grade option—instead of on the low-grade option—is set as the default. This effect is particularly strong for board choices. In contrast, solo travelers are not affected by high-grade defaults. Solo travelers show strong and stable preferences for high-grade board categories and low-grade room categories. These findings provide practical implications for how travel companies can benefit from default options to promote the sale of higher-graded—and thus higher-priced—travel packages.

Based on Unconscious Thought Theory, our study shows that unconscious information processing can improve the quality of personnel selection. Unconscious information processing led to objectively better decisions than conscious processing, even though two cues that often bias personnel selection were present. whereas many studies show that attractive and male job applicants are preferred, we found no gender or attractiveness bias under unconscious decision making. in contrast, conscious decision making reflected a gender bias and some evidence also points to an attractiveness bias.

Smartphones sind aus unserem Alltag nicht mehr wegzudenken ‐ ihre Produktion aber verschlingt Unmengen an Energie und Rohstoffen und am Ende stehen Berge von Elektroschrott. Beim Studierenden‐Wettbewerb chemPLANT der kreativen jungen Verfahrensingenieure (kjVI) der VDI‐GVC präsentierten die Teilnehmer zukunftsweisende Lösungsansätze für diese aktuelle Herausforderung. Das Team der TU Kaiserslautern überzeugte mit seinem zukunftsweisenden Konzept zum Smartphone‐Recycling mittels Bioleaching unter Berücksichtigung sozialer Aspekte.
