No full textIn two studies, the role of nature experiences and social norms during childhood is explored next to adulthood biospheric values, connectedness to nature, environmental identity, and objective knowledge in relation to pro-environmental behaviors. Study 1 (N = 185) tested the hypothesized model in the realm of general pro-environmental behaviors and sustainable fruit consumption on a sample of students. Study 2 (N = 155) tested the model in the realm of sustainable seafood consumer choice on a general population sample. Path analyses show consistent results across samples. Results show that childhood nature experiences and exposure to pro-environmental social norms during childhood are related to adulthood development of connectedness with nature and biospheric values; these, in turn, help in shaping adulthood environmental self-identity ultimately influencing the enactment of sustainable food choices during adulthood. These findings point toward the relevance of childhood experiences for pro-environmental behaviors as compared to the provision of information. The role of objective knowledge across samples is inconsistent, thus requiring future investigations
A Conceptual Framework for Planning Transhipment Facilities for Cargo Bikes in Last Mile Logistics
No full textA conceptual framework for planning transhipment facilities for cargo bikes in last mile logistics
No full textS.575-582Global urbanization processes expedite a growing demand for more sustainability and higher liveability in cities. New logistic concepts like cargo bike schemes can be a vital means towards this goal. In this respect, both logistics planning and urban planning need to address several aspects of the urban fabric, but show a lack of holistic planning tools. We develop a conceptual framework that combines planning objects and planning scales of logistics planning with urban planning. We demonstrate the application of the framework for the theoretical deployment of an urban transhipment facility (UTF). Drawing upon interdisciplinary expertise from urban logistics, urbanism, sociology and psychology, several interdependencies of an UTF implementation with the urban fabric become apparent. Regarding this, several practical recommendations for the use case can be derived. In general, we recommend the application of the framework as a guideline for urban and urban logistics planning purposes to practitioners and encourage scientists to further develop and enrich the framework

No full textAre professionals rationals? : how organizations and households make e-car investments
No full textThis study attempts to identify the main drivers for e-car investments in households
and organizations. We questioned 227 decision makers in households currently considering car
purchases, and 101 decision makers in small businesses. The businesses were private care services,
because their driving profiles widely fit the capabilities of modern e-cars. The main investment
drivers were compared in an integrated action model involving elements of the theory of planned
behavior and the norm-activation model, i.e., investment intentions, attitudes, personal (ecological)
and social norms, and perceived behavioral control. For each group, different models were calculated
in order to investigate the relevance of different types of social norms within the decision process, i.e.,
injunctive or descriptive norms. As expected, the household and organizational decisions were found
to be based on different key factors: the decision makers in households mostly considered personal
and descriptive social norms; the organizational decisions were mostly grounded in attitudes and
injunctive social norms concerning staff expectations. The results suggest the need for tailored policy
measures for each target group.OVGU-Publikationsfonds 202

On new physics in Delta Gamma(d)
No full textMotivated by the recent measurement of the dimuon asymmetry by the DØ collaboration, which could be interpreted as an enhanced decay rate difference in the neutral B d -meson system, we investigate the possible size of new-physics contributions to ΔΓ d . In particular, we perform model-independent studies of non-standard effects associated to the dimension-six current-current operators (d̄p) (p̄′b) with p, -rfpag′ = u, c as well as (d̄p) (τ̄τ). In both cases we find that for certain flavour or Lorentz structures of the operators sizeable deviations of ΔΓ d away from the Standard Model expectation cannot be excluded in a model-independent fashion. © 2014 The Author(s)
